Powerful rear hub motor and easy conversion

I installed this ebike conversion kit on my old bike, and the rear hub motor performance is excellent. The hub motor kit came with a solid control unit, pedal sensor, brake lever,s and LCD, and installation was straightforward. The battery pack givesa good range ,and the motor weight is well balanced on the rear wheel. It really turned my regular bike into a smooth electrically assisted pedal cycle for daily commuting in the UK.

Perfect for most bikes and very safe

This electric bike conversion kit fit my frame perfectly and works with disc brake and different wheel sizes. I like the battery design and option to buy the battery separately in different battery sizes. The system feels safe, light weight, and powerful with a responsive sensor and smooth power boost. Great quality and suitable for riders who want a complete e bike feel without buying a new electric bike.

Strong power and off-road performance

I chose the rear hub version for more torque and off road riding. The motor, controller, cables, axle and bracket are high quality components and feel very durable. Installation around the non drive side was simple and the display shows speed, range and battery clearly. This is one of the best bike conversion kits I’ve tested — powerful, reliable and compatible with most bikes.

Pleasantly surprised

I had low expectations not for the e-bike kit but for anything that’s road legal in the uk! This kit massively exceeded my expectations. Easy to fit, easy to set up and has changed my 3.5 mile Devon hills commute from an arduous hilly 25mins to an 11 minute leisure ride. I don’t expect it’ll be long before I swap out for a higher wattage kit either 1000w rear wheel or mid drive.

Nice kit

Great kit and excellent customer support. I ordered a 2500W–3000W kit with a 60V setup, and the hardware I received was actually a higher-spec controller, which shows the overall build quality and performance potential of the system.I personally prefer a different connector style, but that’s purely personal preference. I’m currently waiting on a second set of torque arms before riding, but overall I’m very happy with the product and the support behind it. Highly recommended.
