    Gutless bike motor
    Worthless product and worthless support! I installed it on two different bikes with at 36 volt battery with the same result–no boost whatsoever. Tires are fine, no slippage when running, just no power whatsoever at any speed. I messaged for support and requested to return it complete with photos, but I was told I was too late to return (a week too late).

    A little under powered
    Ok, but somewhat under powered, otherwise ok.Serves the purpose.

    Small motor. Pedaling helpful.
    Works fine. No problems. I knew that with 250 watts I would still have to do some pedaling.

    Sewage Chunk
    This garbage chunk didn’t work for two seconds. The controller comes disassembled, and they expect you to clip wires and rewire the controller. The instructions are on a video that is entirely in Chinese where you can see nothing. I hate Amazon for putting this fraudulent chunk of sewage up for sale. I have asthma and a heart murmur and dreamed of having help biking, but this horrible toilet of a product did not work at all.

    Solid build and it definitely gives you the boost you need for up hills however the installation process was vexing as I had to retrofit a metal adjustment band to keep the motor affixed firmly. Buyers beware of this or you’ll go through the same frustration I did..
