Greenspeed highly recommend the use of ‘clipless’ pedal systems, as they provide a safer attachment to your trike and help to reduce leg fatigue. Remember you are on a trike now so you can crank the tension up on those adjusters, as you only have to dismount at the end of your journey instead of every set of traffic lights.
The first ride is where you may notice yourself having a hard time keeping a straight line at speed. Try relaxing your grip on the handlebars, remember it is not a bike you are riding, so let that killer grip off a bit. Try avoiding pulling on the handlebars as well, you are riding a recumbent now, the seat provides a place to exert all your energy. Remember push into the seat not pull on the handlebars. If the problem persists, try riding using only one hand to steer, as this will stop you pulling unnecessarily on the handlebars.
Fitting your trike through tight spaces, doorways etc, can be made easier if you push/ride your trike through diagonally. The diagram (below) shows how this reduces the width of your trike.
