Most electric bikes have a chainring in the 40's usually 46 or 48. I have bad knees and in my triple non electric bike I almost never use the larger chainring. I'm much more comfortable in the 28 or 38 chainring even if the gear inches are about the same. When trying out electric bikes I seem to be straining when in a step thru in a relaxed or upright position which all the ones I've tried are. Whereas a similar stepover with a forward position seems to be less straining and more comfortable, but some of them are hard for me to mount. Is this an issue for anyone else? If so which ebike would you recommend trying out?
