Unboxing and What’s Included

When I opened the package I found a well-organized kit with the major components protected and labeled. The wheel came already laced and trued to the rim, the controller was potted and sealed, and the TFT color display and wiring harnesses were neatly bundled.

I appreciate that they include basic assembly tools — a crank tool and M8 hex wrenches — which made the swap feel more thoughtful for a DIYer. Small items like the XT90 connector and screw-locking motor connector reduce the number of extra parts I had to source.

Packaging and First Impressions

The kit arrives heavy and dense; the hub feels robust in my hands and the rim has good weight to it compared to thin single-wall rims. The potted controller gives me confidence about waterproofing and long-term durability. The TFT display felt clear and legible, and the harnesses were long enough to route cleanly on a typical MTB frame.

I noticed that the motor axle and hardware are built with heavy-duty stress points and that the connectors use secure locking features to reduce accidental disconnections.

Installation Process

I installed this on a 26-inch hardtail frame with 135mm rear dropouts. The process is straightforward for someone comfortable with wheel swaps and basic wiring, but it does require attention to torque arms, chainline, and secure electrical connections.

I’ll walk through the steps I used and mention common pitfalls I saw on other installations.

Step 1 — Prepare the Bike

I removed the rear wheel, checked the dropout condition, and confirmed the frame spacing is 135mm. I cleaned the dropouts and inspected the derailleur hanger alignment.

I always recommend a torque arm for powerful hub motors like this one to prevent axle twisting under heavy torque.

Step 2 — Mount the Motor Wheel

I inserted the axle into the dropouts and ensured the wheel sits square. The 135mm dropout spacing is standard for many mountain bikes, so fitment was straightforward. I tightened the axle nuts, ensured proper chainline, and reinstalled the derailleur adjustments.

Because this motor produces significant torque, I secured a torque arm and used medium-strength threadlocker where applicable.

Step 3 — Install the Freewheel and Chain

The wheel comes with a 7S freewheel already installed. I aligned the cassette/freewheel, looped the chain, and made sure the derailleur indexing was accurate. I adjusted the B-tension screw to maintain good clearance between the derailleur and the cog.

If you prefer a different gear ratio, check the freewheel compatibility and double-check freehub threads before changing anything.

Step 4 — Mount the Controller and Route Wires

The controller is potted and waterproof. I mounted it under the top tube using sturdy zip-ties and vibration-damping material. I routed the wiring along the frame, secured it at regular intervals, and used the XT90 for the main battery connection.

The harness used screw-locking motor connectors for the hall/sensor and phase leads, which helped avoid loose connections.

Step 5 — Install the TFT Display and Configure

I mounted the TFT display on the handlebar, routed the cable to the controller, and clipped it into the display mount. The initial power-on allowed me to set language, wheel size (26″), and some basic PAS and throttle behaviors.

I checked the wiring connections and confirmed everything powered on correctly before spending more time tuning.

Step 6 — Test Ride and Fine-Tuning

I initially rolled the bike on a flat area to check for unusual sounds, motor cogging, or wheel imbalance. I tested PAS levels, throttle response, and brake cutoffs. After a 10–15 minute low-speed ride I rechecked axle nuts and connector tightness.

Allow some time for final adjustments to brake levers, chain tension, and display settings after the first ride.

Wiring and Electrical Setup

The electrical side matters a lot with a high-power kit. The controller is rated at 48V and 2000W with a continuous current of 25A and a maximum surge capability of 50A. That means your battery must be able to handle short bursts up to 50A safely.

I strongly followed the recommendation to use a battery with a 50A BMS. The kit uses an XT90 male connector on the kit side; make sure your battery either uses an XT90 or you install an XT90 on the battery harness. The screw-locking motor connector for halls and phases makes the motor wiring secure.

I also recommend installing an inline main fuse sized for your continuous current (for example around 30–40A depending on expected use) between the battery and controller for added safety.

TFT Color Display

The included TFT color display is a surprisingly useful component. It presents speed, trip information, battery voltage/state-of-charge, PAS level, and basic fault codes in a clear, daytime-visible screen.

I liked that the display has configurable wheel size (set it to 26″), easy PAS-level switching while riding, and a throttle indicator. The menu navigation is straightforward and I could change assist curves and max current in a few steps.

Display Functions and Usability

The display is bright enough to read in sunlight and the menus are logically arranged. I toggled through PAS levels, monitored battery voltage during high-power climbs, and used the display to check for error codes when I experienced a wiring issue in early setup.

If you’re used to simpler LCDs, the TFT’s color and graphical clarity make status-checks faster and less fiddly.

Motor Performance on the Road

The motor delivers aggressive, immediate torque. From a stop it pulls strongly and maintains high torque well into moderate speeds. The listed loaded max speed is about 55 km/h (roughly 34 mph), which aligns with what I observed on flat runs with favorable gearing and a decent battery.

Acceleration is where the motor stands out; hill accelerations and quick sprints from stops feel effortless. The combination of the controller’s peak 50A capability and the 2000W motor means I could maintain high power without overheating the controller quickly thanks to the potted design.

I noticed the motor has a characteristic direct-drive hub feel—low noise at cruising speeds, a small amount of cogging at very low RPM, and a slight hum under heavy load. For an off-road-capable kit, the sound profile is acceptable.

High-Speed Stability and Handling

At speeds approaching 50–55 km/h the bike required attention to wheel trueness, tire choice, and braking. The 26-inch double-wall rim is solid and behaved well under speed, but remember that a heavier hub motor changes handling dynamics and rotating mass.

I tuned suspension and tire pressure accordingly to maintain stability. Good brakes are a must; I upgraded pads and bled the hydraulic system to handle the increased sustained speeds.

Hill Climbing and Urban Commute

This motor will change how you approach hills. I climbed steep, sustained grades that would have been difficult on my unassisted setup. At PAS levels 3–4 with a strong battery, I could maintain climbing speeds that kept me ahead of typical mid-power e-bikes.

In urban commutes, the throttle provides quick merges and confident acceleration. The 7S freewheel and proper gear selection kept cadence reasonable while the hub supplied torque.

Range and Battery Considerations

Range depends heavily on how I used the power. Because the motor is capable of 2000W and peak currents up to 50A, range varies more than with low-power kits. I tested three usage profiles:

• Conservative cruising: 48V battery, 20Ah (960Wh). Riding at an average draw of ~400W (gentle assist, flats), I saw 2–2.5 hours of runtime and roughly 60–90 km of range depending on wind and elevation.
• Mixed use: same battery with moderate hills and PAS levels 3–4 averaging ~800W draw, I saw around 1–1.2 hours and 30–50 km of range.
• Aggressive use: heavy throttle and high-speed runs with frequent hill sprints averaging near 1200W, the range dropped to around 20–30 km.

Because the controller can pull up to 50A in surges, a battery with a 50A BMS or higher continuous discharge rating is ideal. I wouldn’t run this motor on a battery with a 20–30A BMS unless I limited the controller’s current via settings. For long rides I recommend 20Ah+ packs and planning for recharges if you expect to use high assist.

Controller and Electronics Quality

The controller is potted, which means the components are sealed in epoxy. I appreciate this for off-road riding and rainy conditions: potted controllers resist moisture, vibration, and small impacts. The result is reliable operation and fewer intermittent connector issues.

The waterproof connectors are IP66 rated, and the kit claims a full waterproof approach. In practice I rode in wet gravel and light stream crossings and saw no functional issues. I still avoided submerging the controller or connectors, and I checked connections after heavy rain.

Build Quality and Waterproofing

I judged the mechanical build as robust. The hub shell and axle appear machined to withstand high torque, and the spokes and double-wall rim combination feel solid under load. The freewheel threads and cog fit are standard and should work with typical MTB drivetrains.

On waterproofing, the potted controller and IP66 connectors instill confidence. I saw no water ingress in normal wet-weather conditions. Still, long-term exposure to mud and salt needs regular cleaning and care.

Compatibility and Fitment Notes

Compatibility is straightforward if you have a 26-inch frame with 135mm rear dropout spacing. The wheel is built for 26-inch rims and fits tires 1.75″ to 2.95″, so most MTB tires will work.

A few considerations:

• Dropout width must be 135mm. If your bike is longer or shorter you’ll need adapters or a frame modification.
• Use of a torque arm is strongly recommended because the motor produces high torque.
• The kit uses a 7S freewheel. If you want a different gear setup, check compatibility and thread types.
• Ensure your rear derailleur can handle the freewheel and that chainline works with the motor axle spacing.

Safety and Legal Considerations

I treat this kit as a high-performance conversion. In many jurisdictions e-bikes above certain power or speed thresholds fall under motor vehicle or speed-pedelec regulations. I checked local laws before riding and I recommend doing the same.

Also remember:

• Fit a fuse and consider a BMS that handles the peak current you expect to draw.
• Use mechanical safeguards like torque arms.
• Upgrade brakes and ensure proper helmet and protective wear for higher speeds.

Maintenance and Troubleshooting

Maintenance on this hub kit follows common hub and electrical checklists:

• Regularly inspect axle nuts and torque arm for tightness.
• Check connectors for corrosion and secure fit.
• Re-true the wheel occasionally; heavy torque can slowly loosen spokes.
• Monitor the controller temperature in long climbs. Although potted, it still generates heat.
• If the display shows error codes, consult the manual and check hall sensor wires, battery voltage, and phase/ground connections.

Common issues I encountered during initial setup were primarily wiring or display configuration rather than motor failures. Ensuring correct polarity, secure screw-lock connectors, and XT90 connection orientation solved most problems.

Pros and Cons

I lay out the main strengths and trade-offs as I experienced them.

Pros:

• Very strong torque and acceleration; excellent climbing.
• Includes TFT display and necessary connectors.
• Potted controller and waterproof connectors increase durability.
• 26″ double-wall rim provides solid wheel strength.
• Good accessory inclusion (crank tool, M8 wrenches).

Cons:

• Requires a battery capable of handling 50A peak; not suitable for low-discharge packs unless limited.
• Heavier than a standard wheel; handling and unsprung mass change.
• High speed may require upgraded brakes and safety gear.
• Legal restrictions in some areas due to power and speed.
• Installation may require a torque arm and some mechanical skill.

Who This Kit Is For

I’d recommend this kit to:

• DIYers comfortable with mechanical and electrical installation who want serious performance from a 26-inch MTB setup.
• Riders who prioritize hill-climbing and higher top speeds over strict range economy.
• Off-road riders who want a durable, waterproof controller and connectors.

I would not recommend this kit to:

• Casual commuters who only need low-power assistance for short trips and want the lightest possible setup.
• Riders using batteries with low continuous discharge ratings without planning controller limits.

Practical Tips and Best Practices

I picked up several practical tips during installation and testing that I want to pass on:

• Always use a dedicated 48V battery with a BMS capable of at least 50A or limit the controller’s current.
• Fit a torque arm even if your frame appears solid; it’s a small safety investment.
• Upgrade brakes (pads, rotors, bleeding) before attempting sustained high-speed runs.
• Use high-quality XT90 connectors and keep a small roll of dielectric grease on hand for exposed connectors to resist corrosion.
• Re-check axle nuts and connectors after the first 30–50 km of riding.
• Set the display wheel circumference to 26″ for accurate speed and odometer readings.
• If you want quieter operation at low RPMs, experiment with different assist curves or lower PAS levels.

Real-World Scenarios I Tested

I’ll summarize three test scenarios I ran to give you practical sense of performance.

1. Commuter sprint: 10 km mostly flat, half throttle-assist, PAS level 3. Result: average speed ~28 km/h, battery drop moderate, comfortable acceleration, no overheating.

2. Mountain climb: 600 m elevation gain over 6 km with sustained steep portions. Result: maintained 12–18 km/h on steep sections, controller ran warm but tolerable, battery sustained current with a 30Ah pack.

3. Fast road run: long stretches at 45–55 km/h on minor roads. Result: strong performance but noticed increased wheel and brake demands; battery drained fast at sustained high power.

Troubleshooting Checklist

If you encounter issues, here’s a concise checklist I used:

• No power to display: check XT90 and main fuse, measure battery voltage.
• Motor hums but no rotation: verify phase wires and hall sensor connectors.
• Error codes: cross-reference with manual; check for low battery voltage or loose connections.
• Overheating controller: ensure ventilation, reduce sustained high-current output, or consider larger heat-sinking or fan options (if available).
• Wheel wobbles under load: recheck spoke tension and axle nut torque.
