    I wasn't sure which ebike I wanted, but the guy at Ebike Generation helped me understand each of the models, the different frame designs, and how the different batteries. I ended up choosing the Jetty, and I'm real pleased with it so far. I think I want to get a second battery, because i don't want to wait for it to recharge every time. But that's so minor. Thanks again.


    Very convenient

    Great little bike, I stick it in the car and take it with me. ideal for city errands


    Fun and Easy

    I love the bike. It is fun and it is fast I cannot believe how much easier it is to make it up hills. I am ready to do the Tour De France. Everybody should own one of these. I am disabled so this bike is great if you have problems with your legs as much as I do.


    Great for errands

    I use my Jetty for running in town errands. It is cheaper than starting my car and wasting gas (and all that other good stuff). When folded up I can fit it easily in my closet and out of the way.
