The Jiabailie 700c 48V 1000W conversion kit is a gearless, brushless rear-wheel drive hub motor designed specifically for use with a 700c wheel on a road bike. The conversion kit includes everything needed to install the hub motor and associated electronics, including a 48v display with five levels of assistance and throttle response, brake levers with cut-off switches, and a remote throttle.
Installation of the kit is relatively simple. In addition to the electronics, the kit provides a complete rear wheel including rim, spokes, and tire. Simply remove the old rear wheel, mount the new wheel to the bike using existing quick-release skewers or nuts, connect the electrical connections, tighten the skewers or nuts, and test.
The hub motor is designed to provide high-speed performance. According to the manufacturer, the maximum assisted speed is approximately 30 miles per hour. This is likely higher than most users will ever achieve, but it gives some indication of how fast this motor is capable of going. It should be noted that this motor will have enough torque to pull the average adult uphill if ridden slowly enough.
For example, assuming a 200-pound rider with no cargo, even a moderately steep hill will likely allow the user to climb the hill by maintaining a steady cadence while pedaling. Additionally, because this motor is gearless, there are fewer mechanical components that could fail over time. However, this also means that the motor is heavier than a comparable geared motor.
Overall, this appears to be a well-designed product that will meet the requirements of many ebike enthusiasts. It has a very competitive price point relative to what is currently available in the market.
Specs and Build Quality
What you get in the box is worth spelling out. The Jiabailie kit ships as a complete rear wheel assembly with the hub motor already laced in, plus the brake levers with cut-off switches, a remote throttle, an LCD display with five levels of assistance and throttle response, cable connectors, and mounting hardware.

The motor is rated at 1000 watts and has a weight capacity of 264 pounds. Because it is gearless and uses advanced bearings to support rotational motion, it is expected to be highly reliable and require minimal maintenance. As always, proper care and storage of the motor will help extend its service life.
Installation and Compatibility
This conversion kit is designed for use with a 700c wheel on a road bike. It fits 700c and 27.5 x 2.8 wheels, and fits most frames with quick-release or thru-axle compatibility. The electronic controls included in the kit can accommodate batteries ranging from 24v to 72v.
According to the manufacturer, this hub motor has been tested at speeds of up to approximately 25mph under controlled conditions. Based upon customer reports, actual speeds may exceed 35mph depending upon terrain and riding style.
Due to its significant torque output, this motor is suitable for climbing hills. While individual results will vary based upon factors such as terrain grade, rider weight and strength, and tire type, customers report that they are able to maintain reasonable cadences while climbing moderately steep grades.
What Amazon Reviewers Are Saying
Based on reviews and comments from multiple sources, it seems that this product performs exceptionally well both mechanically and electronically. Users report consistent reliability and excellent acceleration performance. One user did comment on some vibration felt through the handlebars at low speeds, however this issue was resolved after adjusting the tension of the derailleur cable. Overall, it appears that this product is a great option for anyone seeking to convert their bicycle into an ebike. It offers exceptional value for its price and meets virtually every requirement for successful operation in most environments.
To be fair, the variant page for this specific kit does not currently display a rating, which usually points to a newer listing or a thin review count. We do not want to pretend there is a stack of verified owner reports when there is not. What you are buying is assessed on the spec sheet and the design rather than a crowd of testimonials. That is not automatically a red flag, it just means you are taking a bit more of a chance than you would with an established, heavily reviewed brand. If you are comfortable being an early adopter and willing to read the manual carefully, this is a fair trade for the price.
Who Is This Kit For?
This is a commuter kit first. The combination of a gearless motor, a five-level display, and a complete prebuilt wheel means there is very little that can go wrong mechanically. Bundling the controller, throttle, and brake levers together removes most of the guesswork from a first build. For someone who has never converted a bike before, that completeness is worth a lot on its own.
It is also worth weighing the weight tradeoff. A gearless motor of this size is heavier than a geared alternative, so expect the rear of the bike to feel different on the first few rides. None of that is a dealbreaker, but it is honest context for what you are buying. You will also want a 48-volt battery rated for the current draw, so budget for a quality pack. If you are a casual rider who just wants a gentle boost, a smaller 250 to 500W motor would serve you better and cheaper.

Frequently Asked Questions
Does the Jiabailie kit work on a 700c road bike?
Yes. The kit ships as a prebuilt 700c or 27.5 x 2.8 rear wheel, so it drops into most road and hybrid frames without re-spoking. It fits most frames with quick-release or thru-axle compatibility, but check your dropout width and axle spacing against the listing before you order.
What battery do I need?
Any 48-volt battery can be used with this kit. The electronic controls can accommodate batteries ranging from 24v to 72v, but battery selection will depend upon desired range, personal preference regarding noise level and weight distribution, and overall cost considerations. A quality pack is worth the money, since a weak battery becomes the bottleneck at full throttle.
How fast will it go?
According to the manufacturer, the maximum assisted speed is approximately 30 miles per hour, with test speeds reaching around 25mph under controlled conditions. Based upon customer reports, actual speeds may exceed 35mph depending upon terrain and riding style. Real-world speed depends on your weight, tire pressure, wind, and battery health, but this is a fast kit, not a slow one.
Is the motor gearless, and does that matter?
Yes, it is brushless and gearless. No internal reduction gears means fewer parts to wear out over time, and the motor uses advanced bearings to support rotational motion. The tradeoff is a heavier motor compared to a geared unit of similar power.
Is it hard to install?
No. In addition to the electronics, the kit provides a complete rear wheel including rim, spokes, and tire. Remove the old rear wheel, mount the new wheel using existing quick-release skewers or nuts, connect the electrical connections, tighten everything, and test. The comprehensive instructions and mounting hardware make the job straightforward.
How much weight can it carry?
The kit is rated for a 264lb load. That covers most riders plus a rack and panniers, which is plenty for a daily commuter setup. Factor in the weight of the motor itself when you balance the bike, and make sure your frame and rack are rated for the combined load.
