E- tadpole Triker
Hi Folks
This is the current project
a "dismantlable " to transport and store trike that will be easy to assemble and carry around , This is not a folding trike and has 3 main bits , The rear end with suspension , the cross boom , and the front crank boom
It has disc brakes all round but has been designed with a form of Direct Knuckle Steering that comes up from the brake arms , At present in a prototype form so we can see if there are any problems .
the initial idea is not to fit a front changer and to fit the rear disc brake as a parking brake and the rear gear lever in a place where it can be operated on the rear frame and keep the weight below 40lbs assembled .
The 20/20 e-trikes fit in the car and with a bit of a struggle on the roof , But being a one piece trike they takes up a bit of room when not in use( 7 ft x 3ft approx ), so the plan is to make a trike that takes up less space when not in use .
A light weight trike built from smaller tubing and uses the down tube from a larger diameter MTB frame BUT still retaining 20" wheels all round for a reasonable smooth ride and the "fullsize " look .
Unfortunately the photos are not in the correct order as the Thread editor wont allow me to shuffle the pictures around
The cross boom is 40 mmx 20mm with centre point steering angles cut into the boom , In the centre there are two anticrush tubes to ensure the boom remains strong when the bolts are tight and wont deform and the caster angle has been cut into the rear section of the main boom ( 40mm square ) , but the front boom ( 35mm MTB down tube ) is also angled 5 degrees down so the bottom bracket does not sit too high , there is more than adequate clearance without any possibility of heel strike ( 17.5 " ) and folding pedals will be fitted to make storage simpler .
So How far have we got ?
:- the trike is almost there with all the main things fitted except for the front brakes , They are merrily swimming over from China alongside a tea boat ( or something like that ) This build will be using LH and RH pit bike brake calipers and brake levers .
But we have everything thing else ready to assemble apart from a few brackets , The chain line is now sorted as the chain was trying to machine away one of the rear chain stays but an extra pulley has corrected this ,
Probable another 8 hours to get the trike " on the road " and then 50 or so miles sort out before stripping and painting ,
apart from a mirror and a removable flag pole there will not be a rack at present it is starting to look like a trike
Further updates as the build progresses ,,,, watch this space ......
