I’m going to be riding my bike almost exclusively on beaches, but will encounter hills to and from the beach. I can’t seem to find exactly what I need in one bike. After much research, I know what I should be looking for, but not sure of priorities. I’m a bigger gal, so I need a powerful motor for the hills. I’m on my own, so battery for distance is important to make sure I get where I’m going. And what chain wheel tooth count (not sure of terminology) is best for hills? And how Important is torque and how do you calculate it?The beach environment is an issue, so protection is important, such as the battery installed in the frame, position of controller, etc. I thought the 4 inch tires would be easy, but all the bikes that have most of what I want USED to have 4 inch tires, but now are 3 inch (rad mini, rize bolt x). The Rad people said I could put 4 inch tires on the rims, but is that really a good thing? The Rize people said you could not put 4 inch tires on the bolt x rims. Support is an issue for me, too. I live over 90 minutes from any bike shop so phone support (preferably US or Canada would be good). I do have one ace in the whole and that is a guy at an e-bike rental place in a nearby town who can assemble, maintain and do some customization. He is a certified e-bike technician, which is great, but don’t want to be totally dependent on him, once I have it set up. I have considered Yamee (Rattan) - questionable service. Rad Mini, Rize Bolt X - not 4 inch tires. Kutty X - the amp number on battery is lower. Surface 604 Twist, only 500w motor. Elux Sierra Gt, but on another forum thread, people said the parts were cheap for the price. Safety is super important too, so is the the twist throttle or trigger throttle safer for a dork like me who didn’t know what a throttle was until I started researching e-bikes? Thanks for any ideas/advice.
