E-Trike Project

Yes, this bit is very subjective

Boring holes around the neutral plane of the beam shouldn't weaken it very much, though.

Thanks doc And have had a lil read through, rather technical for a 'dummy' like myself hehe... I wont be drilling holes in them however i like them how they are now, its not a 'high performance' vehicle its a cruiser, largest bumps it will encounter are cracks in the footpath/cyclway and up here they are all very new the shire has been replacing the paving with niiiiiice concrete ~1800 wide, i cross the road directly out front of my house and have my own 'personal highway' right to the main shopping center ~3km away (and the local pub) I'm sure they will work just fine as is Cheers for comments...

Small Update

This morning I went and bought 8 x 28mm OD 12mm ID sealed bearings (AU$47.00) to be used on the trikes suspension and rear axle assembly.

This afternoon I knocked up the housing that will be welded to the frame, the swing arm assembly will attach to this. I took a series of pics to show how I went about making the housing that will hold the bearings-->



As can be seen the tubing is slightly larger than the bearing OD and was a sloppy fit. I cut the tubing with a a 1mm thick cuttoff disk on the 4inch angle grinder , popped the tubing in the mini vice beveled the edges and welded it back up, the fit is near as perfect I can get it with the tools at my disposal and imo more than good enough for the job it will do. A smaller OD tubing was fabricated and tacked in place to keep the bearings in place.

Shall chop the frame tomorrow and weld these housing in place before continuing work on the rear suspension assembly/axle housing.

Back with update on days work tomorrow

Love those orange bearing seals

[AussieJester]

Pitty wont be seen when all assembled though

I also neglected to mention, my order from TNC Scooters (motor controller throttle sprockets chains etc etc etc) cleared Australian customs on the 20th so not too far away... All excited I is

Update

Stuffed about for TWO HOURS this arvo (thanks ALOT miles ... LOL ) getting the mod to the swing arm pivit location on the frame aligned and even on both sides ONLY to stuff the mitre up on one of them (see circled joint in pic below) I was too annoyed to redo the whole thing today BUT to make the mood more cheerful again my order from TNC Scooters arrived-->



As you can see folks I have already ::cough:: relabeled hehe the 1000watt motor to something the local law considers "legal"

Back tomorrow with another update...

I love the curves on your frame.

On Mk II you could make a continuous sweep through the pivot point so that it echoed the curve on the front front

Cheers miles and there wont be a 'MkII' this will be it for two wheel at the back trike... Building 3 generator windmills after this to provide power for my workshop/converted garage/apartment/where i live LoL to run the pc, lights, and tools in workshop...then a beach buggy (600cc petrol motor) project with a mate then ill think about a revers trike (two wheels at front) but it wont be recumbent style...be upright along these lines http://www.brudelitech.com/pictures.htm (except electric powered) If i can figure out the tilting front wheel setup SO...if you have design alteration Mr Miles SIR speak NOW or for ever hold your peace hehehe...cheers for the suggestions thus far to mate much appreciated, my suspension should work better for it anywayz LoL...

[1000w]

Nice to see that motor etc. I love the work on the 200w sticker.
Cheers,
Matt.

[Miles]

It's not something that's easily alterable now and it's a pretty subtle cosmetic thing so, in the circumstances, I think I'll hold my peace....

PS You'd better doctor the Current rating, as well

That looks like a pretty overbuilt 24V motor. I think it'll take 48V juuuuust fine.

[docnjoj]

You're a better man than I am , Gunga Din.......... I woulda used a dutchman on that space and filled the hole with auto filler! I hate doing things over! Nice label. Sounds like the start of a cottage industry
