Hey guys! So lucky to have access to such a great website and community. I'm a bike messenger based out of New York and thought it was a good idea to invest in an electric bike/system. Weekend days, I ride upwards of 50 miles in a single day. After a while, it began to take a toll on my back, I ultimately ride 200 miles a week. Initially I was looking for an entire bike for $3,000 but haven't found a single one that can manage a 50 mile range. If you know a bike that fits my budget and has 50 miles or range, please comment. I've stumbled upon the BionX D-500 and it seems to be the choice to go with. I figured I'll most likely be converting my bike. Should I go with the BionX D-500? Based on the reads, BionX seems to be the industry leader. Will it be able to handle 10,000 miles in a course of a year? How much would I have to spend on maintenance? There are other conversion kits that cost significantly less, around $700 for 25 miles. I was thinking on installing two slots for batteries, like the Riese & Müller bike https://electricbikereview.com/riese-muller/delite-gt-nuvinci-hs/ and make it more affordable. Are their other routes I can take? Thanks for reading. Please feel free to share.
