E- tadpole Triker
Hi Folks
This year we decided to build a couple of smaller BUT still full size electric tadpoles for our holiday .
The builds were a success and the trikes came on holiday with us , and performed perfectly . the main problem we had with our bigger trikes was that they were too heavy and just a bit too big to fit in the car or worse to lift onto the roof rack . With that in mind we built a 24 inch ( pedal ) trike first and that was just too big to fit inside for comfort . Then we were given a couple of 20" Kids mountain bikes and with a bit of adjustment of the dimensions we built the first of the 20/20 e-trikes , During the first build we eliminated some of the problems of a non-dismantable trike and with a bit of planning the first trike was born and used , before the 2nd build we were modifying the original trike and upgraded it . Left over were some of the original build pieces which were then built into the second trike ,
The trikes use 37v lithium batteries and the red one has a q100 motor but the black one has a ez-go Izip motor running 37 volts rather than the original 24v but the hub motor that was living in the rear of a 16" wheel is now living in a 20" wheel , the reduction in torque offset by the increase in voltage still gives a good performance in the rear of the trike .
The trikes would have front disc brakes and under seat steering and be able to be lifted by one person into the rear load space of a mondeo estate .
Both trikes were built from 40mm 16g square tubing and have solid seats rather than mech seats that take up a bit more room .

the start of the little bits
The wheels started life on a BMX bike and were modified to accept disc brakes

once the little bits were cut and made it was time to weld up the frame , starting with the main boom and the 20" mountain bike rear end

a week later and the trike looked like a tadpole
The handlebar were cut and shut from the bmx and from a pair of mtb bars and the under seat steering assemble built from an old hub and a chopped down stem the most time consuming part is cutting the compound angles into the cross boom for the centre point steering which includes both caster and camber angles to be worked out
