  Defiant Bike

By Roger c. on January 09, 2021

I love my defiant bike, it is a heavy duty bike ,750 watt, 20 inches wheels, 55 lbs, foldable and used to have it in the back seat of my toyota camry all the time ,just remove and charge the battery and kept it in my car all the time. Before I had the defiant I bought like two electric bikes,both end up damaged and sit now as junk in my parking garage. I strongly recommend this electric bike ,I have it like 5 months till now and have like 2200 miles in total on it. It is fun and reliable as an electric bike and you can go like 35 miles very easily on it per battery charge and you can enjoy a very comfortable and smooth ride on it. Thanks Roger

By goheenbecca on January 08, 2021

I love my Defiant Ebike. It is comfortable, dependable, durable, and takes me where I want to go. Such a beautiful thing. You can pay a lot more, but will not get a much better bike. I own a white one, they now sell camaflouge too. I like white for visibility. I recommend this bike; too much fun!
