I really don't know. I've only had e-bikes in the last year & already had bad experiences w/ these: ECOTRIC (throttle just stopped working the very 1st time took it riding, so fortunately able to return by the 14-day rtn policy) & MOTIV (had various troubles about 3 mos into buying w/ bike shop repairs about 8-10x's) & now stuck w/ them, but they're working for the moment. I was very close to getting Rad Power Bikes, but decided against it because I felt rushed since the models I wanted were discontinued, so it was just a temporary feeling of wanting to snap them up. But I did thorough research & they probably would have been pretty good. I heard Lectric was crap. Most brands are going to be good the first few mos or so many miles.
I think the saying still goes, that you get what you pay for for the most part & $1000 up to even 1500 is a little too cheap. I'll sve up till I can pay more. We know nothing on this earth is perfect, a person just hopes when they choose a product to buy, whether it be a car, computer, or bike, that it's going to be something that will give us the LEAST amt of problems. To this day, I'm still learning of new brands I've never heard of before.
