The White Warrior - 40mph+ tadpole trike FINISHED!

[MagerPain]

The 9c is cool, but I'd like better acceleration. This motor at 100v in a 20" rim would be lovely, in a 26" it's a bit sluggish to accelerate for my tastes.

Xanda, that's pretty much what I'd have guessed. My 26" eBay hub motor is ok once at speed, but the pickup rate is far from exhilarating. But still, the price is right I suppose. Any plans for a 28S LiPo bank?

this website has a great blueprint for one, and the instructions are alot more precise then AZ

honduran_kid, that site was probably the biggest influence on my design, my front wheel bridge proportions are pretty much identical to this one. I've put a post on ES showing my build if you're interested: http://endless-sphere.com/forums/viewtopic.php?f=6&t=41804




Cheers,

28S? Nah. I may well go for 24s, or some kind of chain drive...we'll see

KMX trikes are selling for around $800.
Minus the e-bike components, how much did your's cost to build?

 

[Xanda2260]

Erm, and probably about £300. Front wheels alone cam to £160 once I paid shipping and import duty...

Would you recommend the Atomic plans to others or do you think there is a better set of plans?

I have atomiczombie plans and they are well written, beautifully illustrated, and intuitive, but building a trike is way more expensive and a hell of a lot tougher than you would think. Of course most of this isn't the plans fault but largely the fault of the idiot behind the welder but the camber/caster/Ackerman angle tolerances are really tight and I found that after I got everything welded up I was off by just a few millimeters in a few places but it just makes everything handle like garbage. My home built atomiczombie trike looks awesome and totally works, but when the performance envelope is pushed my atomiczombie trike is definitely not something I want to go skittering around a corner in, or go on long rides in. My factory build KMX Typhoon just has everything lined up perfect making the thing handle like a sports car and bucket style seats are way nicer than my scratch built foamy planks.
I really like my KMX trike and after attempting a scratch build I think the asking price of a KMX is worth it. I think this because on my atomiczombie build I spent $200 on wheels, $200 on disc brakes, and another $200ish or so on the rest of the materials (steel, foam, fabric, brake lines, chain, ect…). Maybe you can do better on sourcing cheap materials but I blew a good $600 or so to get my atomic build rolling down the road compared to the $700 I spent on a used but infinitely superior KMX Typhoon.

I have to second that about the build process itself: I've built a few things now, including CrazyBike2 and Delta Tripper, and though I dind't actually *try* very hard to make them perfect, they most definitely aren't.

It took enough effort just to get things to work as well as they did; I imagine that when I do this from scratch (eventually), it's going to be a lot harder, and take at least one rebuild of whatever I start building, once I find out which things I screwed up in the process.

Even if you manage to cut all the pieces exactly, and align them perfectly, it's still possible to mess things up during the welding process, with uneven heating/etc causing things to twist or warp just a little bit, which can significantly affect putting the rest of it together past that point. (and how it performs even after you manage to shove it in place and get it welded).


Now, if you were to use a *bolt together* plan, instead of a weld-together one, at that point all you have to do is cut and drill them right and they'll all make exactly what the plans show.


THat said, I've seen a lot of happy builders that used the AZ plans for their builds (complete or as a basis and modified), around the web. So they're good plans...just that it takes the skill of an experienced builder to actually make them as intended.
