So now I'm on my 2nd EV, after having built a BMC kitted, triple butted nice steel framed mountain bike, (with help from endless-sphere and Ilia). It quickly got converted to a street bike when I couldn't get any traction in the woods due to an on/off throttle, and front wheel drive, doh!
When I found out I needed a Medical Mobility Scooter I did a weekend of internet research to find the coolest, fastest, best power to weight ratio M.M.S. available. After having raced all my life I wasn't going to get myself a granny mobile! I found it, it's a Triad 750; 750W 48V hub motor, 65lbs (33kgs), including battery. It'll go 25mph (40kms) stock, sitting upright, so of course my racer brain went into modification mode, because it's big flaw is that it's a short wheelbase, delta trike and so very unstable in corners. My first thought was to put clip-ons on the front suspension forks, extend the chassis by at least a foot, and turn into a 30" high "kneeler", add a "dustbin" fairing and go for some speed/efficiency runs, plus go to some EV events.
Another thought I had that I'ld appreciate any feedback on, is to put a thrust bearing in the extension, (lazy suzan on it's side), so that I could lean it into corners like a motorcycle and shift my weight inside like a motorcycle racing sidecar rig.
Can't seem to put the jpg on this post.
This is really good quality scooter, all stainless fasteners, nice stiff chassis, a throttle that modulates perfectly from crawling to wide open, great lights, seat, alarm, horn, 3 speed settings, front suspension forks (yes front suspension forks!), and seriously FAST! I'm laying all kinds of darkies at work, the thing'll spin the front wheel for like 50 feet!!! :shock: :twisted:
 
As an ES'er, you know you've got an obligation to crank the power and speed up on that thing, even if it already seemed adequate. ;)
 
Yeah !
Build a drift trike with a cromotor
Who said medical mobilility shouldn't be fun :twisted:

ABSOFUCKINLUTELY! But living in the Great White North, (EH!), I'll have to wait for a few months until I can ride it outside just to make use I have of the speed stock. Even in the BIG old 50's factory I work in, I can only only hold it wide open a second or 2 before I have to brake so as not splat into a wall or machine, the painted floors are fun though I can mark them up for a "goshdarn" long way. But the delta trike handling characteristics can catch you out pretty quick and there's no steering when you're up on 2 wheels! :shock:

So any thoughts on my tilting/thrust bearing/kneeler/extension/mod? :wink: :idea:

I'll be asking your advice how much I can overvolt it and cool it too, come Spring. :mrgreen:
 
I got a Triad 750 and I gotta say I'm impressed; 750W 48V hub motor, in a 16" wheel, 65lb package with suspension forks, really nice quality all around. Being at the start of our Great White North winter I wont get to ride outside for a few months, but already I'm thinking of mods, chassis mostly, (delta trike-BAD handling).

But I'm curious if anyone else has bought this scooter and modified it on ES?
 
More than a little Off Topic but I couldn't resist. It's very funny and it expresses the virtues of high powered delta trikes.

These segments of BBC's Top Gear really make me laugh.

Better hurry up and order one before they get sued out of existence. 25 mph on that thing is a guaranteed product liability lawsuit :)

Sorry to say but that's something that's totally wrong with your country-to many idiots "protected" by too many Bloody Lawyers! If people are idiots they should learn from their mistakes/stupidity without "protection" IMHO.
 
So I did my first modification; went from a cheapass 140mm disc brake setup, to an Avid BB7 200mm disc brake set up. It required more work than I thought, the Avid's disc bolt circle is slightly smaller than the stock one so I've had to slot the holes up a little. To get the disc on I had to cut the the hub motors wires, (5-22 gauge, 3-18 gauge), and put them back together with bullet connectors, making it easier for future wheel removal. Now I've been looking into maybe using a heavy duty mountain board, "channel" truck, on the back axle to be able to lean it. What I'ld like to find out is should I just do a front wheel lean (a la "Carver"), or use a channel tuck on the back wheels, or both?
