Bought two rad ebikes, commuter and step through before Christmas. We live in Kansas, not a lot of hills but lots of wind. I am 71 and wife is 68. No issues with putting them together and with some relatively mile weather (40 and 50) we have ridden almost every day up to 20 miles. Love the experience. Pedal assist the wind (25 mile an hour the last time we rode). We have a contest to see who is using the least pedal assist. Has been a great experience, can't wait till spring.
