I order 15/8, they send it 24/8 it arrived 4/9 in two different packages to avoid tax Fantastic motor, perfect acceleration, and high top speed With the gear sensor, the bike shifts the gears very soft. The display (DP C18) has 5 speeds. On my bike the top speed is on no.1 27km/h, no.2 is 37km/h, i have not tested the others yet. I have 26-inch wheels and a 44 teeth sprocket. Be smart and put on a new cassette and chain and dont take away the front derailleur, look at the picture, the chain can drop without that. My bike weighed 11kg before and 20kg after.

Very powerful engine. I am satisfied with this engine and I recommend the seller. He answers quickly all the questions. Thank you

7 days after placing the order today the package arrived at home. packed very well. All taxes are really handled by the seller. Good communication with the seller, which perfectly speak English. I recommend it really to order from this seller

Super powerful and flexible product. Easy assembly on a B'twin 7 of 2009 in 26 ". Seller very appreciable and fast (received in fifteen days).

Such an amazing motor. I am loving every bit of it. First, the shipping was super fast. It took 11 days to Sweden via UPS. The products were neatly packed and everything was fine. It took me about 5 hours to rebuild my bike and it was such an amazing experience to ride it afterwards. I have ridden the bike for 100km in 3 days now. It is really powerful. Goes really fast too. And the Pedal assist is amazingly helpful. Battery does about 70km in one charge with assist. Hope after a few cycles it will get better. Everything is good. The seller was really helpful with questions. He was quick to respond. Highly recommended. One tip: buy the gear shift sensor along with. It will help you avoid grinding gears during shifts and will definitely give a long life to the bike.

I am very pleased with this mid-drive conversion kit. The ride is extremely smooth and the motor is quiet. Installation was pretty easy, I just needed to borrow the correct tools to remove the old cranks. The kit has a lot of wires, but I used cable management tubes (like you would use behind a TV or computer) to make it look a little more contained. While I'm using it the battery percentage really fluctuates, but it will settle out when the bike isn't moving. Overall, I'm really happy with this purchase.

Installation of this motor was easy and straight forward and the seller will give you installation video guide. I did not run into any serious issues while installing it. I did have to mount the battery upside down since the mount has the holes placed too high up. The 750 watt motor is very powerful and gets me cruising up to 30mph when at max power. I did purchase the smallest chainring and have 26-inch wheels so it could very likely reach 35mph. The motor does have a very noticeable delay after you stop pedaling but when you hit either brake, it will instantly cut off the motor and stop the spinning.

I recommend this product, a very good device to help my activity
