Works perfectly for my rear wheel, and they even sent some extra screws. Thank you!
A miracle of engineering. Sellers sent a wheel motor kit with a faulty controller. I opened a dispute, confirmed the malfunction. The seller honestly sent me a new working controller. There is only one remark: I ordered a throttle with an ignition switch and keys, but they sent me the usual one. Despite everything, I praise the seller. I put a set of electric motor wheels on a bicycle.
