FAQ

Great E-Bikes!

We have two of the Defender SMRFS Bikes and absolutely love them! We RV fulltime and they are the best for keeping outside. I love that they have an alarm and wheel locking. Plus, it's so great that they can withstand all types of weather.

We use these on pavement and all types of trails. They are really comfortable to ride and so fun to use. I highly recommend them!

The Defender does everything

I have the SMRFS Defender ebike. I would describe it as a do everything and do everything well ebike. The build quality, fit & finish is high. With the step through frame and adjustable handlebar stem it will fit a very wide range of riders. The battery has a decent range (especially if you put a little pedal power in) but you can add a second battery without being an electrical engineer. The tires are 3" wide so it is wide enough for any terrain but not as heavy and as high a rolling resistance as true "fat" tires. The acceleration and top speed are about as fast as you want to go on a bicycle. Brakes are hydraulic, which is expected at this price point and performance. I have ridding it 200 miles so far with no issues. My only complaint is that I do not like the seat. I changed it over to a different one but they also offer a suspension seat post and a comfort seat as upgrades.
