I'm recovering from having both knees replaced and wanted an e-bike to help in my rehab. This bike has been exactly what I needed to get me back on. I don't believe I would have ridden much at all without the "peddle assist". I can do between 5-10 miles easily on the battery and basically just use the power on hills and inclines. I've not needed to contact the company for any customer service in the 6 months I've had the bike. My husband (not a bike mechanic) was able to set it up after having a local bike shop switch out the wheel. I'm very happy with the bike and have told everyone I know its a great alternative to buying an expensive e-bike. It suits my needs perfectly.
