Hi,

I'm gonna visit my LBS tomorrow and would like some advance advice... I'd like to be able to peddle along instead of using only the throttle, but unfortunately, I'm unable to peddle any faster than 7mph in the top gear (6th) because at that point I'm just "spinning my wheels". Do I just need to change out the crank for a bigger one? Sorry, I don't know too much about bike mechanics.

Thanks!

Change your Chainring, not crank. Good luck.

Had to change the whole thing out because it's 1-piece. I'm able to hit 15mph via peddling now.
