Excellent performance

I may say this is really a good ebike, I mainly use it to go to work. I have a Jasion EB5 for almost 4yrs before it broke down (something about the motor), so I decided to buy this one which is really cheap for the price and the performance is excellent, you can really feel the difference. I hope Jasion would consider giving a tail bag for being a loyal costumer for 4yrs.
