Cargo Bike Purchase Question
Hi there!! I'm in the market for a cargo e bike as an upgrade to my lower end first e bike purchase previously made. It had a 500W rear hub motor that was more than enough for me. The bike im currently looking into the most is the new to the market Yuba Fastrack. Love the back end use to it and vertical storage is always appreciated. My only issue is its motor. I live in a VERY hilly environment where hills can have a grade of 15-20 in places where I may need to stop and start. The Fastrack comes with the Shimano e7000 with 60Nm of torque. Will this be enough to get me through those types of hills? I do food deliveries and bike regularly. Also if anyone is aware of if after a year or two of use, which Shimano motors can I place in the frame that are the same size as the e7000, would the EP8 or e8000 fit?
Thanks so much for the help!
