Great Customer Service
I purchased an A275 model about 6 months ago. My wife and I both use the bike almost every day. The bike is very comfortable, and it has not had any issues. We are living in a steep city. Hydraulic brakes are powerful enough to stop the bike at high-angle downward steeps, and the motor is powerful enough to take you through steeps. Recently, there was a problem with the battery, and after contacting customer service, they are going to send me a new battery without even charging for the shipping fee, which is an example of great customer service.
