My Tadpole Project (update--overdue)

Thanks guys.

No art here..... just lots of homework....I'm looking for a system that works, for me. (I am keeping with my 'UGLY' theme....UGLY = Anti-theft)

throttle cable....... now that would be handy!!
yeah, that's on my 'to do' list. (right now, I am using the 'suicide' throttle. SET IT & Forget IT.....till I need to slow down!!)

Stay tuned for a Trike Rally in 2010 !!

Large, thanks for the shifter tip. (Josh, at my LBS has a bunch of nos 3 speed shifters & stuff, too.) I have some questions for you about the powered 3 speed.

I'm almost ready to start two more trike builds..... pedal only.
Kinda like this----> (cept different)

I have plenty of new steel & a nice set of front wheels for one of them.

Nice job just one thing...its back to front :-| real men ride deltas hehehe

Serious mate top effort, look forward to seeing her all painted up, just about got my trike back together after looooong downtime painting :: sigh ::

Trike with 79cc 2.5HP engine

How fast does it go? It looks like that engine is suiting you well for the trike.

BTW, it's a very gas efficient engine. My bro gets 135MPG and 38mph so far with the one on his pusher trailer. It's a little sluggish at low speed, but once it's going, it's quick.

You will enjoy the MPG and quietness of this engine for sure. In the very near future, I plan to retire the 6.5 and use a 2.5. I'm just wondering how well you like the performance.

Boy, was I wrong!!

I don't have the shifter set up on my jackshaft, yet.... so I am stuck in 1st gear.

Without the shifter hooked up....I was in 3rd gear, on the 'jackshaft'. DOH!!

I was semi-pleased, in 3rd....I mean it pulled itself, but the engine never really had a chance. haha LUG--LUG--LUG

After hooking up the shifter & finding 1st gear....for real, this time....I must say---WOW!!

Disclaimer: I realize having gears on a motor assisted bicycle is illegal, but in the name of 'science' ,(& in search of an adequate gear reduction for a 3600 rpm max engine) I felt it necessary to use the 3-speed hub.

also...I may mention speeds that are illegal also...be gentle guys...it's science...hahaha

I have no need, or desire to go mega-Fast.

Okay..... 1st gear..... I gotta be gentle on the take-off.... lots of 'lowend' power. I was paced by a guy in a cage.... in excess of 30 mph.
1st gear pulled the RR overpass, like it was flat ground.

I've shifted to 2nd twice.....& gone up to 1/2 throttle.....I have no clue how fast, but I wanted NO MORE !!
nor do I want 3rd gear.

Hopefully, 2nd gear will make a nice overdrive for Highway riding.


Soon, I will crunch the numbers & find out exactly what my gear reduction numbers are.

How's the steering? If it's a bit "twitchy", using bar extensions to change the handles from vertical to horizontal might help.

the steering seems pretty smooth, but I like the idea of bar extiensions... more choices to put my hands...more comfort. & if it makes the steering better than it already is....that's a PLUS !!

So 2nd gear is fast. Cool!

Does it still pull in 3rd, for low-rpm cruising?

Well, I finally gathered enough parts to redo my drivetrain. The 3-speed jackshaft served its purpose... allowed me to find the gear reduction I need.

I'm going with a slippy-belt from the engine to a jack shaft...then #41 chain to the rear wheel.

Wish me luck & a kick to my backside for motivation !!
