A front wheel hub motor conversion kit for 700C road bikes and hybrids that costs less than a decent set of tires. That is the Jiabailie 700C 48V 1000W kit in a nutshell. The Jiabailie 700C conversion kit on Amazon targets the budget end of the market with a complete front wheel package that includes the motor, controller, display, throttle, and brake levers. No battery included, but everything else is there.
Specs and Build Quality
The Jiabailie kit uses a brushless gearless direct drive hub motor rated at 1000 watts continuous. Front wheel configuration means the motor replaces your existing front wheel entirely. The wheel is 700C, which is the same diameter as standard road bike and hybrid bike wheels. Also fits 28-inch and 29-inch frames.
Claimed top speed is 45 to 55 km/h, which works out to roughly 28 to 34 mph. Real world speed depends on rider weight, battery voltage under load, and terrain. Expect the lower end of that range with a standard 48V battery and a typical rider.
The motor casing is aluminum alloy. That keeps weight reasonable for a direct drive unit. Gearless hub motors are heavier than geared hubs of the same power rating, but they have fewer internal parts to fail. No planetary gears to strip or nylon teeth to wear down. The tradeoff is some cogging drag when you pedal without power. That magnetic resistance is normal and you get used to it quickly.
Load capacity is listed at 264 pounds. That covers the rider plus any cargo. The axle uses standard flat dropouts with machined flats for torque arm mounting. Front wheel torque arms are essential for a 1000W front hub motor. The axle can spin in the fork dropouts under hard acceleration and that will damage your fork. The kit does not appear to include torque arms, so add those to your shopping list.
The kit includes a 5-speed pedal assist system. That is a nice feature at this price point. Most budget front hub kits ship with a throttle only or a basic 3-speed PAS. Five levels give you finer control over how much help the motor provides. Level 1 is a gentle nudge for extending range. Level 5 is full power for climbing or getting up to speed quickly.
Cruise control is another feature you do not usually see on kits in this price range. Activate it and the motor maintains your current speed without holding the throttle. Nice for long straight stretches where you want to rest your wrist.
The display shows speed, battery level, trip distance, and PAS level. Basic LCD unit. It works. The readout is readable in direct sunlight based on the product images. The display mounts on the handlebar stem or next to the grips.
Installation and Compatibility
Front wheel hub motor kits are generally easier to install than rear wheel kits. You do not have to deal with the drivetrain, derailleur, or freewheel. The Jiabailie kit follows that pattern.
What you need to know before buying:
The kit is designed for 700C wheels. That means road bikes, hybrid bikes, touring bikes, and some gravel bikes. It will not fit 26-inch mountain bikes or 20-inch folding bikes. Measure your current wheel diameter and check your fork dropout width before ordering.
Front fork dropout spacing is the critical measurement. Most road bike forks have 100mm spacing. The Jiabailie motor axle needs to fit that gap. If your fork has quick release dropouts, you may need to verify the axle diameter matches. The kit uses axle nuts rather than a quick release skewer.
Installation steps:
- Remove the existing front wheel and tire
- Install torque arms on both fork legs
- Mount the Jiabailie wheel and tighten the axle nuts
- Mount the controller to the frame or inside a frame bag
- Route the motor cable along the fork leg and down tube
- Connect the display, throttle, PAS sensor, and brake levers
- Connect the battery and test
The brake levers included in the kit have integrated motor cutoff switches. When you squeeze the brake, power to the motor cuts immediately. The levers are basic plastic units. They work. If you prefer your existing brake levers, you can install separate brake cutoff sensors instead.
The controller is a separate rectangular box. It needs mounting somewhere on the frame. Under the down tube is the most common spot. Use zip ties or velcro straps. Do not use metal hose clamps that could damage the frame paint or pinch the wiring.
The wiring harness uses color coded connectors. Phase wires, hall sensor wires, throttle, display, and brake cutoffs all have matching plugs. No soldering required. The whole wiring process takes about 20 minutes if you take your time routing the cables neatly.
What Amazon Reviewers Are Saying
The Jiabailie kit has no reviews on Amazon yet. That is the reality of a new listing from a lesser known brand. No feedback to draw from, positive or negative. We will update this section as reviews come in.
For now, the lack of reviews is something to factor into your decision. Established brands like Voilamart and Ebikeling have hundreds or thousands of verified reviews. You pay more for that track record. Jiabailie is offering a very competitive price in exchange for taking a chance on a newer product.
Who Is This Kit For?
This kit is for the budget conscious road bike owner who wants electric assist without spending more than the bike is worth. If you have a 700C hybrid or road bike sitting in the garage and you want a cheap way to electrify it, the Jiabailie kit is one of the most affordable front wheel options available.
The 5-speed PAS and cruise control are genuine value adds at this price. You are getting features that usually cost more. The front wheel format keeps installation simple. No drivetrain complications, no freewheel to swap, no derailleur alignment to worry about.
Who should skip it:
Riders who need maximum torque for steep hills should look at rear hub or mid-drive kits. Front hub motors have less traction under power because the front wheel carries less weight. On loose surfaces or wet roads, the front wheel can spin under full throttle. That is a characteristic of all front hub motors, not specific to this kit.
Builders who prefer the reassurance of an established brand with a long review history may want to spend more on a Voilamart or Ebikeling kit. And anyone with a 26-inch or 20-inch bike cannot use this 700C wheel at all.

Frequently Asked Questions
Does the Jiabailie kit include a battery?
No. You need a separate 48V ebike battery. The kit includes the motor wheel, controller, display, throttle, PAS sensor, and brake levers. Budget 150 to 250 dollars for a quality 48V battery with proper cells and a BMS.
What bikes does a 700C front wheel fit?
Road bikes, hybrid bikes, touring bikes, and gravel bikes with 700C wheels. Also fits 28-inch and 29-inch frames. Does not fit 26-inch mountain bikes or 20-inch folding bikes. Check your fork dropout spacing before ordering.
What is the top speed on flat ground?
The manufacturer claims 45 to 55 km/h, which is roughly 28 to 34 mph. Real world speed depends on rider weight, battery voltage, and terrain. Expect the lower end of that range with a standard 48V battery.
How does the 5-speed PAS work?
The pedal assist system uses five levels. Level 1 provides minimal assistance for maximum range. Level 5 delivers full power. A sensor on the bottom bracket detects when you are pedaling and signals the controller to apply power. You can also use the throttle independently of the PAS.
Do I need torque arms for a front hub motor?
Yes. A 1000W front hub motor generates enough torque to spin the axle inside the fork dropouts. That will damage the fork. Install torque arms on both fork legs. The kit does not appear to include them, so buy a pair separately.
Is the cruise control useful?
Yes. Cruise control maintains your current speed without holding the throttle. It is handy for long straight roads or bike paths where you want a consistent speed. Activate it with a button on the display or throttle assembly. Tap the brake to disengage.
