I'm really liking my 2018 RadRover after making a few modification for a more forward, less upright ride. Using it for a work out on road, trail & mountain-ish rides -- it's pretty heavy for full-on mountain biking, in my opinion, but you can definitely use it for trail & pavement. Changed out the stock tires due the the pesky thorns in my area, which really helped. Overall, the bike seems like a very well made machine and Rad Power Bikes offers excellent customer service & support, which is a big deal to me. I'm getting great distance with the battery, and it's faasssst when you crank it up! Went for a 30 mile ride the other day and used up only 2 of 5 bars on the battery, but I do like to peddle a lot. If you like a more upright, plush ride then you probably won't feel the need to make any modifications. I'm just used to riding road & mountain bikes so I wanted a more aggressive feel. Happy shopping!
