Unbox and Build the Sixthreezero 1000W Mid-Drive Rickshaw: A Complete Assembly Guide

There are electric bikes, and then there are electric rickshaws built to carry passengers, haul cargo, and redefine what it means to ride with purpose. The Sixthreezero 1000W Mid-Drive Rickshaw is firmly in the latter category. Powered by a robust 1,000-watt mid-drive motor and designed with both driver comfort and passenger experience in mind, this machine is a conversation-starter, a practical hauler, and an adventure vehicle all in one.

If you've just received your rickshaw or you're doing research before pulling the trigger, this guide walks you through the complete unboxing and assembly process, step by step. From getting the bike safely out of its double-boxed shipping container to attaching the optional rear subframe passenger seat, every stage is covered in detail. You'll also find tips for tool selection, notes on hardware you shouldn't lose, and guidance for adjustments that make the ride feel dialed in from day one.

The good news: the 1000W Mid-Drive Rickshaw ships largely pre-assembled. The major structural work is done at the factory. What's left for you is a manageable series of component installations that most riders — even those with limited mechanical experience — can complete with basic tools and a few hours of focused effort.

What's in the Box: Understanding the Packaging Before You Start

The rickshaw arrives double-boxed — an outer shipping carton enclosing a second inner box — a design choice made deliberately to maximize protection during transit. When your shipment arrives, take a moment to inspect the outer box for any signs of damage before opening it. Minor surface scuffs are common and typically cosmetic, but deep crushing or punctures are worth photographing and documenting before proceeding.

To open the box cleanly, use a box cutter to slice the tape along the edges and down the center seam. Work carefully — the blade doesn't need to go deep to free the tape. Once the outer carton is open, you'll find a second inner box secured around the bike. Remove the top layer of packaging to access the contents.

Inside, you'll find the following:

• The rickshaw frame and drivetrain assembly (largely pre-built)

• The front wheel

• Rear passenger seat with fenders

• Driver seat (saddle)

• All fender components

• Pedals (marked R and L)

• Battery charger

• Mirrors (left and right)

• Seat post

• Headset decorative cap

• Quick-release hardware (if applicable to your model)

• Front basket (shipped in a separate box, included with the 1000W model)

• Owner's manual and documentation

Before anything else, snip every zip tie securing components to the frame. This is easy to overlook, and it's the most common reason parts seem stuck or won't move freely during assembly. Pay particular attention to the zip ties around the tires — there are often more than expected, and they can be difficult to spot on first pass.

One useful trick for removing the bike from its box without damaging the packaging: cut a "garage door" flap into the front of the outer carton. This allows the rickshaw to roll out cleanly while keeping the box largely intact — handy if you ever need to store or ship the bike again. Be mindful of the exposed staples along the box edges, as these can scratch both you and the bike's finish.

Tools You'll Need

Having the right tools ready before you start will save significant time and frustration. The assembly doesn't require anything exotic, but specific sizes matter. Here's what to have on hand:

• Allen keys (hex wrenches): 4 mm, 5 mm, 6 mm

• Open-end or box wrenches: 8 mm, 10 mm, 11 mm, 14 mm, 15 mm

• Phillips head screwdriver

• Ratcheting wrench or socket set (highly recommended for the rear seat bolts)

• Box cutter with a sharp blade

• Wire snips or scissors (for zip ties)

• Floor mat or soft surface (to protect the bike and seat during assembly)

A second pair of hands is genuinely helpful for a few of the steps — particularly front wheel installation and mounting the passenger seat. While neither is impossible solo, having someone assist with alignment and holding components in place makes the process cleaner and faster.

Step 1: Installing the Front Wheel

Front wheel installation is the first major assembly step, and the approach varies slightly depending on your specific unit. Current production models use a bolt-on axle, which is the more straightforward option: the axle slides into the fork dropouts and is secured with bolts on both sides. Earlier units may have shipped with a quick-release mechanism. Both work well — the method simply determines the hardware you'll be working with.

Before positioning the wheel, check the brake caliper area. There will be a piece of cardboard or foam packaging inserted between the brake pads — a protective spacer that prevents the pads from accidentally engaging during shipping. Remove this before installing the wheel. Leaving it in place is a common mistake that prevents proper brake function.

With the packaging removed, orient the wheel so the brake rotor aligns with the caliper opening. As you lift the wheel into the fork, guide the rotor carefully between the brake pads — this requires a bit of patience and is one of the steps where a second person makes things easier. Once the axle is seated in the dropouts, secure it according to your hardware type.

For quick-release axles: slide the axle through the dropout, place the spring on each side with the narrow end pointing inward toward the hub, thread the nut on by hand until you feel resistance, then close the lever with firm palm pressure. A properly tensioned quick release should require meaningful effort to close — if it closes too easily, it isn't tight enough. The lever should leave a slight imprint on your palm when properly set.

Spin the wheel by hand and confirm it rotates freely without rubbing against the brake pads. If you hear or feel contact, check that the rotor is centered in the caliper and that no packaging material was inadvertently left in place.

Step 2: Setting Up the Stem and Handlebars

The handlebar stem ships with protective packaging wrapped around it. Remove all of this carefully using scissors or a box cutter, taking care not to nick the frame's paint or any cables running along the bars.

Before inserting the stem into the steerer tube, check the orientation of the wiring. All cables and wiring harnesses should sit on the outside of the handlebars in their natural routing position. If any wires appear crossed or pinched, loosen the clamp bolts at the handlebar angle and rotate the bars until the routing is clean and unobstructed. Getting this right before tightening prevents headaches later.

There is also a decorative cap that fits over the top of the headset. This piece is primarily aesthetic — it covers the upper stem hardware for a cleaner finished look. Install it before tightening the stem, as it simply presses into place from the top.

To secure the stem to the steerer tube, locate the main bolt inside the stem — this takes a 6 mm Allen key. Before tightening, align the front wheel so it points perfectly straight ahead, checking that the tire and stem are centered relative to each other. Once aligned, tighten the stem bolt firmly. This is a critical connection point; it should be snug, not just hand-tight.

The handlebar angle is controlled by two bolts on the face of the stem, which take a 4 mm Allen key. These come pre-set from the factory to a neutral position, which works well for most riders. If you prefer a more upright or more aggressive riding posture, loosen both bolts slightly, rotate the bars to your desired angle, and re-tighten. Make adjustments gradually — small changes in handlebar angle can have a significant effect on riding comfort.

Step 3: Attaching the Front Fender and Light

The front fender is identifiable by the mounting tab on its top edge. This tab, along with the front light bracket, attaches to a single bolt threaded into the fork crown. The light mounts behind this tab, and the arrangement — light, then fender tab, then bolt — creates a clean, layered connection.

Thread the bolt through the light bracket and the fender tab, then engage it into the fork's threaded hole by hand. Before tightening, hold upward pressure on both the fender and the light to ensure they seat as high on the fork as possible. This positioning prevents the fender from sagging and keeps the light angled correctly. Tighten with a 5 mm Allen key.

There's some inherent flex in the fender mounting, which allows you to adjust its lateral angle slightly after tightening. The fender's metal is workable enough to hold a manual adjustment — set it so the fender tracks parallel to the tire with even clearance on both sides.

The light's vertical angle is adjusted separately via a Phillips head bolt on the light bracket. Tighten this once you've set the beam angle you prefer. Note that the front light also has a plastic decorative cover that conceals the headset bolt below the stem — install this piece once you're satisfied with your handlebar height, since accessing that bolt afterward requires removing the cover.

Step 4: Installing the Front Basket

The front basket is included with the 1000W Mid-Drive and ships in its own box alongside the main carton. It comes with an optional mesh insert that drops into the basket floor for a finer-grain storage surface — useful for smaller items that would otherwise fall through the wire grid. Whether to include it is a matter of personal preference; set it aside during installation and add it afterward.

The basket attaches to the front of the bike using four Phillips head bolts, two at the front and two at the rear of the mounting bracket. Start by removing the four bolts already in the mounting area on the bike — these are the factory-installed placeholder screws. You'll reuse them to secure the basket.

Hold the basket up to the mounting bracket and feed the first bolt through the basket's front hole and into the corresponding hole in the frame. Start with one corner, thread the bolt loosely, then work diagonally to the opposite corner. Getting two bolts started before tightening any of them makes alignment easier and prevents the basket from shifting while you install the remaining hardware.

As you position the basket, ensure there's adequate clearance between the bottom of the basket and the top of the front light. If the light makes contact with the basket when the wheel turns, loosen the light bracket bolt slightly and lower the light until clearance is restored. Once all four bolts are seated and the basket is level, tighten each one in a cross pattern to distribute pressure evenly.

The original metal bracket cover that was removed in this step can be kept as a spare. If you ever remove the basket — for storage, transport, or cleaning — it can be reinstalled to protect the mounting hardware underneath.

Step 5: Attaching the Rear Fenders — Do This Before Mounting the Seat

This step is easy to skip in the excitement of assembly, but doing so will cost you significant time and frustration later. The rear fenders must be mounted to the passenger seat before the seat is installed on the bike frame. Once the seat is bolted down, access to the fender mounting points becomes extremely limited.

Each fender uses a single bolt with two washers — one washer positioned between the fender and the seat frame on the outer side, and one on the inner side with the nut. Begin by threading the hardware loosely, leaving enough play to slide the fender into its final position.

Positioning is key. For proper tire clearance, the bottom edge of each fender should sit approximately half an inch from the sides of the tire. This spacing creates the right arc and ensures the fender won't contact the tire during rides, even under load. Set both fenders to match before tightening.

Use an 8 mm wrench or socket to hold the bolt head while tightening the nut. A ratcheting socket wrench makes this significantly easier, especially in the tighter spots. Once both fenders are positioned symmetrically and verified at equal clearance, tighten each one fully. Check that neither fender shifts during final tightening.

Step 6: Mounting the Passenger Seat to the Frame

With the fenders attached, the passenger seat assembly is ready to be mounted to the rear frame. The seat attaches using four bolts — each with two washers, one on the top and one underneath — threaded into the frame rails.

Start by setting the seat down onto the frame and confirming that the fenders you just installed align naturally over the rear tires. If they're off, this is your last practical opportunity to adjust the fender position before the seat is secured.

Feed the first bolt through the seat frame's mounting hole from the top, ensuring one washer sits between the seat and the frame. Thread the corresponding washer and nut on the underside by hand. Work diagonally — front left, then rear right, then front right, then rear left — to keep the seat from shifting as you add each bolt. The two rear bolts also engage with additional mounting brackets built into the frame, providing extra structural reinforcement. Make sure all hardware is fully engaged before beginning final tightening.

Tighten all four bolts with a 10 mm wrench on one side and an 11 mm on the other (the bottom nut may vary by unit). These bolts are structural — they bear the weight of passengers and absorb road vibration. Tighten them as firmly as possible, and don't stop until the wrench stops moving. A socket and ratchet handle is the most effective tool for this job.

Once installed, press down firmly on the seat to confirm there's no flex or movement in the connection. The seat should feel fully rigid — any wobble indicates a bolt that needs further tightening.

Step 7: Installing the Pedals

Pedal installation looks simple but has one critical rule that trips up many first-time assemblers: the left pedal has a reverse (left-hand) thread. It tightens counter-clockwise rather than clockwise. This design is intentional — it prevents the left pedal from gradually loosening as the crank arm rotates during normal pedaling.

Both pedals are labeled. Look for "R" (right) and "L" (left) stamped or engraved into the axle threads or pedal body. Match each pedal to its corresponding crank arm before attempting to thread it in.

To start threading, hold the pedal at a slight downward angle into the crank arm hole and begin turning by hand. For the right pedal, turn clockwise. For the left, turn counter-clockwise. Once the threads are engaged and the pedal is hand-tight, use a 15 mm wrench on the flat wrench flats just inside the pedal body to torque it down firmly. Both pedals need to be properly tight — a loose pedal mid-ride is a dangerous situation.

Step 8: Setting Up the Driver's Seat

The driver's saddle mounts to a seat post via a two-bolt rail clamp. Before threading anything, orient the clamp correctly: the curved portion of the seat post head should arc toward the rear of the bike. This is the direction that provides proper anatomical support and natural pedaling posture.

Place the saddle face-down on a soft surface (the packaging mat works well) to protect the padding during installation. Spread the rails apart gently to create enough gap for the clamp to seat onto them. The clamp's indentations — small grooves or depressions on its contact surface — should engage directly onto the rails; this is what holds the saddle securely and prevents rotation.

Thread the clamp bolt in from the front, hold the nut steady at the rear with your fingers, and use a 6 mm Allen key to tighten the connection. Before locking the bolt down, assess the seat angle: a slight rearward tilt (2 to 5 degrees) works well for most riders. Once your preferred angle is set, tighten the bolt firmly. An under-tightened seat bolt will cause the saddle to rotate backward under rider weight — not a comfortable discovery on a first ride.

Insert the seat post into the seat tube, adjust to your preferred saddle height, and secure the quick-release clamp at the top of the seat tube. As a general starting point, your leg should reach near-full extension at the bottom of the pedal stroke, with a slight bend remaining in the knee. This position optimizes pedaling efficiency and reduces joint strain over longer rides.

Step 9: Mounting the Mirrors

The rickshaw comes with a matched pair of mirrors — one for each handlebar end. Each mirror assembly consists of a clamp base that slides onto the bar end and a ball-and-socket adjustment joint that sets the viewing angle.

To mount each mirror, first loosen both bolts on the clamp base using an 8 mm wrench. Slide the clamp onto the handlebar end from the outside, positioning it where it doesn't interfere with your grip or the brake lever. Once positioned, tighten the clamp bolts to secure it to the bar — but use restraint here. The clamp threads into plastic, and over-tightening can crack the mounting body. Firm and snug is the target; the mirror shouldn't rotate when bumped but shouldn't be stripped either.

With the clamp secured, adjust the mirror head to your preferred viewing angle using the pivot joint. Tighten the 14 mm adjustment bolt on the joint to lock the angle in place. Sit in the driver's seat and look into each mirror before finalizing this adjustment — what looks correct standing over the bike often looks different from the riding position.

Repeat the process for the right-side mirror, ensuring both mirrors provide symmetric rearward visibility from the seated position.

Step 10: Installing the Optional Rear Subframe

If you've ordered the additional rear subframe — a popular add-on that extends the rickshaw's carrying capacity — it arrives in a separate box and installs after the main assembly is complete. The subframe accepts either an additional passenger seat or a cargo basket, depending on how you configure it, making it a genuinely versatile extension of the platform.

Preparing the Subframe

Out of the box, the subframe ships with the foot plate already installed. If you plan to carry passengers, the foot plate stays in place — it provides a surface for passengers to rest their feet. If you intend to use the subframe purely for cargo, the foot plate can be removed: loosen the four mounting bolts, lift it free, and secure those bolts back into place to close the mounting holes.

Before connecting the subframe to the bike, install the safety cable. The cable is a critical component — it provides a secondary retention point that prevents the subframe from separating in the event the hitch connection loosens. Thread the cable through its designated channel on the subframe, route it around the bike's rear frame, pass it back through the loop, and tighten the Phillips head fastener that secures it. Don't skip this step; the safety cable is what stands between a firm connection and a subframe detaching mid-ride.

Connecting to the Hitch

With the subframe prepared, slide its hitch coupler onto the bike's receiver hitch at the rear of the frame. The coupler should engage cleanly with an audible click or firm seating. Secure it with the provided clamp, then insert the safety pin through the hitch pin hole. The safety pin prevents the hitch pin from backing out during use — always confirm it's fully seated before any loaded ride.

Give the subframe a firm pull test after securing all connections. With the hitch locked, clamp tightened, safety pin in place, and safety cable routed, the subframe should have no lateral play and no vertical movement. Any looseness should be investigated and corrected before loading the subframe with passengers or cargo.

Final Assembly Checks: Before Your First Ride

With all major components installed, take fifteen minutes to run through a systematic pre-ride inspection. Assembly is complete only when every connection has been verified — not just installed.

1. Front wheel: Confirm the axle is fully seated in the dropout and secured. Spin the wheel; it should rotate freely with no brake pad contact.

2. Brakes: Squeeze both brake levers firmly. The wheel should stop immediately with no sponginess or excessive lever travel. If the lever travels more than halfway to the handlebar before engaging, the brake cables may need adjustment.

3. Handlebars and stem: Grip the handlebars and try to twist them side to side with force. There should be zero rotation independent of the fork. The stem bolt must be fully tightened.

4. Pedals: Confirm both pedals are tight by attempting to unscrew them by hand. Neither should budge.

5. Passenger seat: Apply downward pressure at multiple points on the seat surface. It should feel completely rigid — no flex, no movement.

6. Driver seat post: Verify the quick-release is clamped tightly and the saddle angle bolt is secure. Sit on the saddle; it should not tilt or rotate.

7. Mirrors: Confirm both are clamped firmly to the handlebars and that the viewing angle is locked.

8. Subframe (if installed): Test all four retention points — hitch clamp, safety pin, safety cable fastener, and the clamp bolt. Pull firmly in all directions.

9. Front basket: Verify all four mounting bolts are snug and there is no rattling when you shake the basket.

10. Battery and charger: Connect the charger to verify the charging circuit is functional before the first ride. Consult the owner's manual for initial charge recommendations.

What Makes the 1000W Mid-Drive Rickshaw Worth the Effort

Assembly guides are inherently functional documents — but it's worth stepping back and acknowledging what you're building. The 1000W Mid-Drive Rickshaw is not a conventional e-bike accessory. It's a purpose-built vehicle designed to extend the utility of electric cycling into territory that standard two-wheel designs simply can't reach.

The mid-drive motor placement — centered in the frame at the bottom bracket rather than in the wheel hub — provides a fundamentally different ride dynamic than hub-motor alternatives. Power transfers directly through the drivetrain, giving the motor access to the full gear range. This means climbing hills with a loaded passenger seat doesn't require the motor to fight against physics; it works with the mechanical advantage of the gearing instead. The result is more efficient power delivery, better torque at low speeds, and a more natural, bike-like feel when pedaling.

At 1,000 watts, the motor output is substantial — well-suited to the demands of carrying adult passengers, navigating varied terrain, or hauling meaningful cargo weight. This is not a motor that struggles on inclines or requires flat ground to perform. Riders report confident power delivery across a wide range of conditions.

The passenger seat configuration is thoughtfully designed. The rear bench-style seating accommodates adult passengers comfortably, while the foot plate on the optional subframe ensures passengers have a stable, supported surface during the ride. The fender system provides weather protection for both driver and passenger — a practical consideration that becomes obvious the first time you ride on a damp surface.

The front basket adds genuine cargo utility to the platform. Whether you're transporting groceries, a bag, a small cooler, or photography equipment, the basket adds carrying capacity to the front end of the bike that balances the overall load distribution when passengers are seated at the rear.

The optional subframe takes the rickshaw concept a step further. It transforms what is already a unique machine into a modular platform that can be configured for passengers or cargo depending on the day's mission. The safety cable system and locking hitch hardware reflect a genuine engineering commitment to security under load — not just convenience.

Riding Positions, Fit Adjustments, and Initial Ride Tips

Once assembly is complete and all connections are verified, take time to fine-tune the fit before loading passengers or heading out on a longer route. Small adjustments at this stage pay dividends in comfort and control.

Saddle height is the most impactful fit variable. Set it so your heel rests flat on the pedal at its lowest point with the leg nearly straight. When you shift to natural pedaling position — ball of the foot over the pedal axle — this creates the slight bend in the knee that protects your joints and maximizes power output. If your hips are rocking side to side as you pedal, the saddle is too high; if your knees are bending sharply at the top of the stroke, it's too low.

Handlebar height and angle work in combination. The standard position works for a wide range of riders, but those with lower back sensitivity or a preference for a more upright posture may benefit from tilting the bars upward slightly using the 4 mm face bolts. Make changes in small increments — a five-degree adjustment feels noticeable on the road.

For the first ride, keep things simple: start without passengers, choose a flat surface, and run through all the controls before adding load. Test the motor assist at each available level, confirm both brakes are responsive, and practice low-speed turns to get comfortable with the wider footprint of a three-wheel configuration. The rickshaw handles differently from a standard bicycle, and a short orientation ride builds confidence quickly.

When you do carry a passenger for the first time, start slowly and allow time to adjust to the added weight and its effect on braking distance and turning radius. The rickshaw's stability platform handles passenger weight well, but heavier loads extend stopping distances — a simple physics reality that requires a slight adjustment in riding style.

A Platform Built for More Than One

What sets the 1000W Mid-Drive Rickshaw apart from the broader electric bike market isn't any single specification — it's the combination of serious motor output, a passenger-first design philosophy, and a modular extension system that grows with your needs. The assembly process, while thorough, reflects the engineering depth of the machine. Each component installs with purpose, connects with hardware rated to handle real-world loads, and contributes to a platform that's designed to be ridden hard and ridden often.

Whether you're using the rickshaw for family rides through the neighborhood, last-mile transportation in an urban environment, vendor operations at outdoor events, or recreational touring, the 1000W Mid-Drive configuration gives you the power and capacity to handle it without compromise.

Take the assembly seriously — tight bolts, verified connections, and a thorough pre-ride check are what separate a great first experience from an avoidable mechanical issue. Do it right once, and the machine will reward you with years of reliable performance.
