1) Rule of thumb – if the child is 7 years old they can generally use crank shortners. An easy method for testing this – lower the seat in the stoker position to the lowest point, then have your child sit on the saddle with the crank in the down position. If their foot reaches at least 1/2 of the crank arm in the down position they can use crank shortners. They can enjoy Ride2 or Tandems East crank shortners until age 11 or 12.

2) Ride2 Kiddie Crank conversion is generally used from age 3½ to 7 years. When ordering it is important to know what type of crank you presently have on your tandem, the bolt pattern of the chainring (110mm or 130mm are most common). Also you need to know your seat tube size. Ride2 kiddie crank conversion can do 3 sizes; 1⅛”, 1¼” and 1⅜”, all hardware is provided and it takes standard metric Allen wrenches to install. Installation is usually a 45 minute job. If the child is just 3½ they will need a longer stoker boom, which generally run about $95. An inexpensive way to avoid the longer stoker extension purchase is to flip over the handlebars. Ride2 Kiddie Cranks come standard with 2 crank lengths, standard 110mm (for the very young rider) or 135mm for older children.

Check the width of your crank by measuring down about 3″ with your digital caliper (click here for purchase info) or use the poor man’s caliper (see info here). The photo below shows a crank 37.6mm wide, this crank will work with either the Tandems East Original Wide Crank Shortner or the Ride 2 Wide Crank Shortner.
