What size is your seat tube?
How do you know if your child
needs crank shortners or a Ride2 child kiddie crank conversion?
1) a rule of thumb - if the child is
7 years old they generally can use crank shortners, with the
stoker seat all the way down. 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 you have a shock absorber seat post remove it and
install a normal seat post first). If their foot intersects with at least half of the
crank arm in the down position they can use crank shortners.
They can enjoy Ride2 or Tandems East original crank shortners
until age 11 or 12.
2) Ride2 Child kiddie crank
conversion is generally used from age 3 1/2 to age 7. When
ordering it is important to know what type of crank you
presently have on your tandem, the bolt pattern of the chainring
(either 110 or 130 is most common). Also you need to know your
seat tube size. Ride2 kiddie crank conversion comes with the
ability to do 3 sizes; 1 1/8, 1 1/4 and 1 3/8. 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 3
1/2 they will need a longer stoker boom. which generally run
about $80. An inexpensive way to avoid the longer stoker
extension purchase is to flip over the handlebars. Ride2 kiddie
cranks can be purchased with 2 crank bolt patterns, standard 110mm
(for the very young rider) or 135mm for older children.
