Re: my second bike
A parchute is recommended for cliff jumping with the bike....lol.....8-0
If you have a bike with gears, you can average substantial mileage. But with only a direct drive to your rear sprocket, not as much as you might wish you were getting. I would suggest going to a jack shaft and redirecting the drive to a geared assembly, this will definately inhence your mileage. Good luck, Maximo 8-)
Building the beast is just as fun as riding one.
