I was looking into buying a EMTB bike in Italy. Possible lightly used for a good price. Hang out with some family for a week or so and ride. Ship Home The Europe specs are limited to 15mph , I would like to modify the bike to US 20mph. I can ride some great hills close to home but would like to get there quicker. 5mph is not a big deal in hills but to ride 5-10 miles to get to hills it adds up. Looking at the cube 160 team. Can this be done easily?
