I'm sure I'll get plenty of alternative suggestions and the has probably been covered but I'm a casual cyclist looking for an e-bike for around $1000 for pleasure riding and the occasional ride to work(3.5 miles) . It's not real hilly around here either. I figure the radmission since speed is simpler, likely more dependable long run and has regen but the core 5 with the 7 speeds would be quicker. Thoughts?
