I reached out to echelon regarding parts for my bike. I purchased the bike in Jan of 2021 and have used it about 3-5 times a week since then. I was on a ride and suddenly felt the crank arm a bit weak as it circled around and on the downward rotation it came off. The bolt/screw that the crank arm is screwed onto completely broke off. Echelon says they can sell me the “kit” but I dont know if that includes the bolt on which it mounts onto? Has anyone else had this problem?
