KP_wag Posted April 19, 2018 Share Posted April 19, 2018 Started eyeing up some shitter BMXs on TM to chop up, but the front frame section looks kinda fit for purpose on those trikes. Do you use cut down bikes for the front tube or piece together some mandrel bends? Re motors, can gears be done or not worth the ball ache?

To make life easy, look at drift trikes on trademe...you can normally pick one up for less than $50. A bmx will work, just involves more work and won't look as clean. Gears are fine, but not necessary. Quote Link to comment Share on other sites More sharing options...
Kimjon Posted April 21, 2018 Author Share Posted April 21, 2018 Had an hour or two to waste on this... waiting on cheap eBay clutch. Will also need to buy some #219 chain, though based on the price... it looks like a may as well pull down my pants and start bending over now. 2 Quote Link to comment Share on other sites More sharing options...
Kimjon Posted April 21, 2018 Author Share Posted April 21, 2018 Aliexpress to the rescue! 219 gokart chain... $17 delivered to my door... V's paying $65-$85 + delivery if purchased in NZ! 2 Quote Link to comment Share on other sites More sharing options...
Kimjon Posted April 22, 2018 Author Share Posted April 22, 2018 Whenever designing a mount, I always try to make it look like a C&B...success!!! Oh, its to hold a brake caliper, which goes on this rotor I've repurposed... 5 Quote Link to comment Share on other sites More sharing options...
Kimjon Posted April 22, 2018 Author Share Posted April 22, 2018 Now a limp cardboard C&B isn't any use to anyone, so if you hadn't guessed...time to get some steel out And all done. Needs 2x spacers to centre caliper...but they're still making M6 washers I think? I'm pretty happy with that. Cost nothing but time and using left over miscellaneous bits from wrecked shit I brought for cheap on trademe mainly to get the motors out of for other projects. 5 Quote Link to comment Share on other sites More sharing options...
KP_wag Posted April 22, 2018 Share Posted April 22, 2018 Biomimicry design process at its finest there... Might work better if you flip it up the other way tho 1 Quote Link to comment Share on other sites More sharing options...
Kimjon Posted April 25, 2018 Author Share Posted April 25, 2018 Righto, managed to pick up a larger sprocket and chain for free...best day ever! I machined up this retainer. Then installed the chain and bigger sprocket. And buy installed...I mean, it went straight on! Like as in no fucking around, bolt holes all lined up, the chain was already the perfect size...truly a one in a million chance of that happening. 3 Quote Link to comment Share on other sites More sharing options...

Kimjon Posted May 6, 2018 Author Share Posted May 6, 2018 Okay...kind of got two of these builds on the go now. Making this hub (×2) is how I spent the afternoon. Along with mounting an engine etc... 1 Quote Link to comment Share on other sites More sharing options...
Kimjon Posted May 6, 2018 Author Share Posted May 6, 2018 Engine mount done. Believe it or not...I've got no M8 bolts. These are only the most commonplace bolt there is, but I'm out! So my fancy hubs can only sit by the wheels for now, as I have nothing to bolt them with. Anyway I feel like I made some decent progess on this today. 2 Quote Link to comment Share on other sites More sharing options...
KP_wag Posted May 6, 2018 Share Posted May 6, 2018 Looking good man, what kinda high performance engine you got to push that next one along? Also, how does the clutch work in those things? Im assuming some kinda off the shelf auto thing but where do you appropriate from? 1 Quote Link to comment Share on other sites More sharing options...

The clones are just as good...and cheaper too. Clutch is basic centrifugal clutch off ebay, delivery is free and they are about $40 give or take. My general rule is to buy what's cheap at the time and work around whatever that is. These have cost very little due to a few good scores from swap meets and trademe.

Muncie Posted May 6, 2018 Share Posted May 6, 2018 Theres a shitload of gear for the honda GX engines cams valve springs rods you name it it's out there. Not to expensive to double or triple the power. 1 Quote Link to comment Share on other sites More sharing options...

Trying to keep them simple but stylish. However I always tend to go a bit over the top in the last stages...call it ocd? Quote Link to comment Share on other sites More sharing options...
KP_wag Posted May 11, 2018 Share Posted May 11, 2018 Tasteful tuned length chinese pipes sounds worth it. How fast you been on the tall bike? Bet it's a long way down in the corners Quote Link to comment Share on other sites More sharing options...

Bet it's a long way down in the corners It rides just like a normal(ish) bike once you're on it and moving. Even slow speed is easy, you tend to forget you are on a tall bike. The only thing to watch out for is going uphill where the front can lift. When you stomp down to power up a hill...if and when the front lifts...it's flips real quick! Any more than about 200mm of front wheel lift off the ground and you be in trouble as the leverage is positioned much further back and higher than normal. Good news is if it does flip you tend to just pop backwards and land on your feet while still holding the bikes handlebars. I'd say it was well worth the half a day to make it:) 3 Quote Link to comment Share on other sites More sharing options...
