How far does A-bike move for each cycle of pedalling?

Postby Amuro Lee on Mon Apr 30, 2007 4:19 am

According to the information on http://www.a-bike.co.uk, the dual chain ratios of A-bike are 14:8 and 35:9

15cm × π × 14 ÷ 8 × 35 ÷ 9 = 320.70425cm

That means for each cycle you pedalled on the A-bike, the bike itself moves about 320.7cm forward.

Yes. You are right.

1 pedalling = 6.8 rearwheel rotation = 3.2m move :wink:
