Well, hello everyone. Just joined and am hoping to get some guidance gearing my dad up. Just wondering where to start. Some background on me, etc. I've been riding a Bacchetta recumbent for about 8 years now and still love it (no motor......yet!). I got my dad on a Easy Racer a few years ago, spent a fair amount of time outfitting it with an electric wheel motor. Turned out really nice but he just never took to it. He used it for a few months and fizzled out. Honestly it never had quite enough power (see below) EDIT 6/30: Well now he wants a motor on his Trike, Sun X3. Can a friction be used on a trike? He's going on 70 and would like to get more exercise. We live in a valley which makes it hard for him to ride as it's a steep climb to get out to the flats where he;s more likely to ride. I'm inclined to a gas motor but I really am not set on anything and have no idea what I should be looking at. Any advise would be great. Cheers all.
