I have a Tern BYB S11 folding bike (for easy carriage on trains and comfortable to ride) and have adapted the Swytch fitting by removing the handle bar attachment from the battery holder/control unit and fitting to a wooden board which attaches to the KlickFix front basket bracket so it can be easily detached for unpowered cycling. I have also added a toggle switch in the pedal cadence detector to more easily switch on the motor just for steep hills (I am a long distance cyclist). Delighted with result.
