Mine only worked for 3 rides totalling less than 3 miles now it won't hold a charge and the display is all messed up. I'm 51yo and disabled & haven't been on a bike of any kind in 30 years. The fastest I ever went on it was 11.5 mph as I was just getting used to it but I've been accused on other forums of derestricting it so it would go faster. I had to look up what they were talking about because I didn't even know that was a thing. I have no desire to go any faster than maybe 15mph. I live in a densely populated part of a large metro area with tons of people riding in bike lanes so I'd have no reason or ability to go any faster. Still no help from customer service. I live on disability so this was a major purchase for me so now I have a $1200 bike that's too heavy for me to pedal unless I remove the battery which defeats the purpose. I'm physically unable to ride any bike very far or I'd have just gotten a cheap bike. I wish I'd just bought a Rad instead now. I feel like a dumbass for letting myself be taken advantage of
