I purchased a Radmini just when the winter rains started so didn't get to go on it much. When I did, I would get caught in the rain. I found myself upping the power up to get home faster and that was one of the good things about it.
I've now got almost 400 miles on it and it is still fun. One thing though, I had a flat so took it to the local bike mechanic to get the tires
armored up for the local goat head population. While it was there, I had him do a tune up and he found a problem with the front hub. He fixed it and now the bike is easier to coast and pedal. The brakes
needed adjustment and there were a lot of other little things to do on it.
The mini folds up and I plan to do that when I take it on travels. It will fit in the back of my Ranger pickup. I've got a home made ramp to roll it up on.
I have been using it to run errands around town on and then going out just for fun rides. I haven't run the battery
out of power yet. I can't answer how many miles you'll get on a charge. There are too many variables. For instance you'll use more power on a sandy road, when riding into the wind, when going uphill a lot, etc. I have had it down to two bars left on the display after riding 14 miles on rough, steep roads. I have ridden the same on pavement and just barely used one bar's worth of power.
It is a lot of fun to ride. I use the throttle to get going from a stop. That feature comes in real handy when there are busy intersections to get through. Then I am peddling. I'm finding it ridable even in 90 plus degree weather. You can adjust the assist to make peddling as easy as you want.
I just wish there were current bushes to plug in and recharge the battery
when camping out in the woods!
