very good!!

Excellent engine, very convenient installation kit. There are keys for dismantling the pedals (square) and the frame itself. There is also a wrench for tightening the threaded nut on the motor. If error 21 pops up after installation, check the installation of the speed sensor, the magnet should exactly hit the round part of the sensor.

Everything is fine, received everything intact, checked everything works. Haven't installed it yet, waiting for the bike.

Everything is great, less than a month until the delivery. Varstrom shell, there was no speed limitation, but if there is any, it can easily be removed on most displays. It fits the GT Avalanche without modifications, thanks to the seller for putting a sticker on the 250W motor.

I ordered the engine on March 18, received it on May 1. The packaging is just a branded bafang box, which was played with a bit but couldn't break anything. The set is gorgeous, they even included a carriage puller and a connecting rod puller that I didn't need, and at my request, they replaced the sprocket with a 42-tooth aluminum one with offset. The kit includes everything necessary except the gear shift sensor, also if you need spacer rings to prevent the motor or sprocket from touching the frame, you need to write to the seller. The seller is very communicative and answered all my questions. Also, please note that these motors already come with a CAN bus, and it cannot be programmed with a cheap UART cable. but the start is smooth, the throttle works smoothly without jerks even when pressed to the maximum power, some torque settings allow changing the displays to dpc080 and dpc18. just from the app via bluetooth, I didn't know this and ordered ekd 01, as it turns out, it also allows making such changes from the display menu.
