Hi Phil
These were just 2 of our conversions , I have used a 500w golden pie on a tadpole trike as well before settling on a xiongda 2 speed setup on one of my trikes and 3 q100 motors on the others , I have done about 4 e-bike conversions and half a dozen tadpole trike conversions .
The q100 motors are the most versatile motors and are quite forgiving when it comes to over-clocking them .
Ken is still using the e-shopper after 2 years of use and it is still going , with 4000 plus miles on the battery ( a second hand 37v LifePo4 ) and motor ( £35 delivered from
chain reaction ) a 24v 700c motor running at 37v in a 20" wheel .
So in the last 2 years it is on its 3 or 4th throttle ( now we keep a plastic bag taped over the throttle as it stops the ingress of water when parked outside in the cycle racks at work )
Iit has eaten one set of folding pedals that were replaced by MTB ones and last week it ate its first chain ( it was still usable without pedaling for the journey home on e-power )
Apart from that the rear wheel collapsed last year ( a light weight rim split ) and was replaced by a heavier BMX one redished for the 5 speed freewheel .
More seriously the frame where the rear brake plate is fitted ripped away and I mig-ed it back together and the rack decided to break on the way home on night - the weight of the battery was the cause . It has eaten 2 pairs of cheap tyres before changing over to marathon tyre with slimed tubes .
It has been an exciting and educational project for Ken as it has taught him a lot about the marriage of available parts / maintenance of e-bikes over the past 2 years and how to repair them .
WHAT PRICE EXPERIENCE they say .
here are our tadpoles with q100 motors

Sadly Dennis my father in law passed away (86 ) last month and had only seen the photos of the finished e-bike but was pleased that the 30year old
halfords ( made in Poland ) Apollo had a face lift and was still in service .
