Good morning everyone from NY. It's been a very hot summer here for the most part and the last thing I want is to be the old guy who has a heart attack trying to get in shape in this heat so I am thinking about getting a ebike although I really know little about them but want to learn and prices of new bikes seem favorable now. I have a good bike store near me but they have a limited selection and online prices are lower I do understand they need to make a profit. One. of the bikes I am considering is the Juiced RipCurrent S mostly because of the battery/motor size but I do realize there are compromises with brakes/cassette/deraileurs etc. I am not sure if I would be able to upgrade components if needed with aftermarket parts after all I think the best brakes avails are important I can't see just replacing inferior parts with inferior parts any advice would be very much appreciated thanks in advance
