At the end of December, i picked this Terra Trike Tour 2 up for a cheap price, very little used. My intentions from the start, is to rework it for a straight-forward ebike setup.

I am a physically limited rider with hip issues. I'm not always stable enough for my DH eMTB project that i've already much enjoyed within my limitations (BBSHD build)... as such, i want something for when i'm not doing all that well for just 2 wheels.

As i am just coming off of doing a VERY complicated gas/electric hybrid bicycle project - i don't wish to overly complicate things, beyond reinforcing/replacing components that will need reinforcement.

As i saw it on Kijiji.ca.

As it was brought home... real convenient!

First major purchase for it... the Black Pie assembly.

I am using this as a builder's thread, so i am going to reserve this post with a needs/wants/options post to keep track of it all, going into it.

Some of this will make no sense at all to others - it's an aggregation of ideas in my planning process, only.

  • Replacement fiberglass rigid seat - ordered February 2nd, 2021. Received February 18th, 2021
    • Design/fabricate alternate method of seat frame to install on stock slider base mount. Will require rail type seat back mount, with Heim Joint adjustability to rear seat mount point down to rear fork. Utilize HD rack components, slider rods, if possible.
    • Incorporate Universal LED taillight into upper mount.
  • DRL housings - left over from Project - use for front illumination in front of front wheel booms.

Hi; my probs with Trikes is the handling. Yours looks as though a swing axle mod is possible. I would consider that before putting to much power onto that rear wheel

Problem with handling? In which way?

This is my first go with a Tadpole, or Recumbent Trike design. In the motorcycle world, i've owned several sidecar rigs, including - a high performance rig.. now there's some weird handling to get used to.

The good thing about this wheel/controller - it's programmable. It'll only give out, what's been programmed to allow. ;)

I've already had a season's worth of experience with a BBSHD.. and certainly, there is a fair amount of torque being put down out of 1000w - especially if you get goofy with the thumb throttle in the wrong gear ratio with a mid-drive..

Initially, i eyeballed the Tadpole Trike, with 'extensive' mods in mind.. 26" rear tire with drop-out extensions, possible total rework to rear suspension, etc.. but i did get a few reports back to my inquires that indicated that the frame may be at limits of tolerance with a stock 20" wheel setup. I've decided to take a conservative approach, at least for this project round. If it isn't for me - time/money minimized - if it's for me - i might consider doing something greater than what this frame is capable of. It definitely has some inherent limitations to it, even for a talented shade tree mechanic practiced at upgradeability with a sawzall and a TIG..

In the meanwhile, i'm upgrading what is easily realistic and attainable. Larger tires/contact patches front and rear to start, to better resist push-out with lateral CofG shift, during cornering/turning for example.

Going around a corner, the bike stay flat until it can't. Then it goes all at once, possibly turning over. Most olds don't have a problem due to slow speeds.......but you're putting some real power into it.

Yes, definitely a factor to be aware of, and certainly not to be discounted. If it becomes an overwhelming safety concern, once i've actually got everything set up, i will consider taking the setup further to compensate, in terms of realistic mods. I have some setup ideas on that, that will require a bit of fabrication without destroying the base trike.. ;)

Either increase wheelbase, increase 'anchor weight' of rear end, and/or any number of front suspension/camber add-on changes or increase of width of front end, would help to mitigate.

Flipping a Trike? ... pfft. I flipped my first sidecar rig.. the irony behind that was that i had a broken leg at the time, and i was using the sidecar to carry Crutches, turned into impromptu Javelins... beware landscaper's dirt piles in the gutter, lurking behind a blinding sun beam in a corner.. I'm a Pro at turning things upside-down.

I do appreciate the Safety, behind the Message.

Schwalbe Super-Moto X 20"x2.40" tire came in and mounted, today.

Edit - February 5th, 2021. Lightbar brackets came in, today. Will help with integrating aftermarket DRL's onto front steering booms, for maximum frontal visibility (sorely needed with low to ground recumbent, IMHO).

Edit - February 18th, 2021. Hard-shell seat came in today, from Poland. This beats the speed of a part coming in from Terratrike in Wisconsin... about a 1/10th of the distance. This is going to need a combination of HD rear rack parts, Heim Joints and modification of components to make up a new mounting system utilizing the adjustable Base mount, only. I prefer a more minimalist seat, vs the fabric seat type of this Terratrike.

I also received the Big Ben 2.15" Plus front tires - significantly more cross-section evident.

I haven't made a new update post lately - just iterative updates on existing posts. As such, if actually interested in my posts - recheck earlier to see my additions.

Today, i'm squeezing the front rubber on the original rims - going from the original 1.75" Cheng Shin to 2.15" Schwalbe Big Ben Plus. The Big Ben's are rated for 50mph... not that'll ever get it to that high a speed... but more rubber on the front, might be of stability benefit, with rear-drive. Worthy of the experiment, anyway.

Before:

After:

2.45" Rear, with 2.15" Front. Looks good to me!

Everything so far ordered, with exception of batteries, and the TerraTrike rack i intend to hang them on, have come in.. so i can pretty much get a good start on it, starting now..


Edit February 20th, 2021: The Hard Shell seat that i sourced, i appear to have successfully track-backed to origin Recumbent Trike - this one.

That gives me ideas to make adaptive mounts for my Trike frame, versus the obviously different frame setup of my Terra Trike. The base mount will work - the rear mount however, definitely won't. I'll get it figured out in a day or two of fabricating.

Still haven't finished my Hybrid - just wiring to do, on that... but i've got a new creative 'pretty shiny' to play with this, in this new project.

It begins.. my Assistant's are giving it a preliminary Technical Evaluation, apparently.

Let There Be Light. The DRL's, brought into play on a test basis. This works for me! Great light-throw, just for DRL's.
