Hi I am new to this forum and would like to know if there is an electric assist kit suitable for my Pashleypdq 3 tadpole trike. The trike has been adapted to under seat steering and a front triple chain ring which with the 3 speed up and 7 speed freewheel gives me 63 gears. I am struggling to ride my trike at the moment as my mobility problems have got worse. I Don,t want to give up cycling and have been thinking of putting an electric assist on my trike. I would prefer a crank driven or mid drive as I would like to keep my gears. I have been quoted £1500 for a Sun Star kit but its an awful lot of money considering the two batteries were £300 each and would only last 3 years. Would be grateful for any advice thank you
