was missing the controller bag, Jason quickly responded and asked to give a quick pict completed to prove i didn't receive it and I'm more than sure they would of sent one out but i got it else where due to needing asap, the kit it self has worked flawlessly in this wet british summer where having , absolutely love it thank you!
I completed the installation somewhat clumsily with the patient help of customer support. My problem stemmed from a misunderstanding of the width of my bottom bracket. Anyway, once I got everything working, the mid-motor system performed very well.
Need to protect a second son! I love they are all keyed the same. Makes it easier!
Shipping was fast, and hassle-free. Customer service contacted me to ensure I was choosing a battery that fit my bike (2020 Specialized Roll Elite - Large) to avoid the headache of a return. Awesome!!
The install was easier than I expected when I had the correct tools. I tried to cut corners, and should have opted for better tools the first time (bottom bracket socket). Watch install vids to see the tools you should use. The tools that are included aren’t going to work for a complete install for everyone.
The bike is so fun, I love it!
I have had this motor installed for about 1 month and have had no issues. Easy install. Package came within the time stated. I did get the brake handles sent separately but I didn't need them right away. Motor and battery work great so far after almost 200 miles. Have fun it's way better than buying an ebike with less power. Just make sure your bike is ready and can handle the power. I had to tweak a few things to adjust.
