New Bicycle Trailer with Honda Clone

[ZnsaneRyder]

I just built this new trailer about two months ago. I used the 6.5HP Honda Clone from my old trailer for this new one. Chain Drive is much better than a belt drive.

I took some pics during first build. It's pushing a dual-suspension 26" Pacific Mountain bike, with an upgraded 24" Rear BMX Plastic wheel. It also has a 12V/4V dual electrical system for lights, and car horn.

This bicycle trailer pushes the bike from the seatpost, and get approx 110MPG on average.

It uses a 13x6.5x6 pocket bike wheel. The transmission is a 10T #41 chain Hilliard Extreme Duty clutch, turning a #40 chain, driving a #41 chain 32T rear sprocket on the wheel. 3.2:1 ratio.

The tall gearing gives me very high speeds, but I lube the clutch, so it will slip some at low speeds. I pedal assist with the engine on takeoff, then it takes over. Haven't got exact speed yet, but someone in a car riding next to me said I was going 50.

I have to upload some more pics when I get a camera to take them, as I now have a rack on it that holds a 2 gallon gas can, mini cooler, and backpack for hauling stuff.

It's great transportation. Hardly costs anything for fuel.

That's pretty wacky. Can't say I've ever seen anything like it. lol

cooooooooool
i want 1. would you be allowed to ride it on the road, and say the engine is decoration?

hahahaha lol

Fantastic project, thanks for the details! Have you had any troubles since it's now a motorized vehicle? Or have you addressed them all with signals, lights, and a horn?

How safe does it feel?

 

[Raywelder]

He told me He rides it on the roads all the time.
I'm wondering how it handles pushing on the bike like that.

 

[Raywelder]

And if it rides fairly nice, You ought to build one or two and sell them! 110mpg would sell.

Here's some pictures of my old one. The new 1-wheel trailer handles MUCH better than my old 2-wheel one. The old trailer is more go-kart like. It got me 90-100MPG with a Kevlar V-belt and the same engine. Chain gets more MPG, and looses less power than a belt. That's why my new one uses #40.

I ride it everywhere. It does really well, goes fast, and gets good MPG. I ride the shoulder lanes or bike lanes. Sometimes I ride in the road if there's no shoulder lane. I'm going fast enough, that I don't hold up cars most of the time. I can legally ride it, because it's still a bicycle with working pedals, and I have lights, and most of the time in town, go under 30mph, and it's only 49cc The catch is the pedals. Also if you break something, or run out of gas, you can still pedal! That's the best part.

In the future, I really want to weld up a large frame with another engine, on the frame of the bike, and still have pedals. I already have a junk bicycle frame and some scrap metal for that project.

I built the bike trailers, because, I always wanted to build a go-kart, and I needed transportation, I had a bicycle, so I figured, why not make a go-kart that pushes the bike.


However, I still want a go-kart. hehe

BTW, that 6.5HP is a real beast. It's already worn the trailer tire almost completely bald in the middle, LOL. I love the deep low-RPM grunt of a Honda Clone engine. I also like how it makes so much power for so little fuel consumption, and is very efficient.

Due to my larger tire on my new trailer making my gearing taller, my engine isn't getting to full 5000RPM, but it's still plenty powerful. I actually like that, because now I don't have to worry about over-revving it and floating the valves. My old trailer revved past 5200 max, but would eat the belt after a while, and slip, so it needed the extra RPM at high speed, lol. I could hear the valves float, and it would just run like that, setting it's own limit, and has never blown up. This poor engine has been through hell and keeps on going. Now I'm easier on it with the RPMs.

I'm seriously trying to get a hold of another few Hondas or Clones, running or not. They are bulletproof.

EDIT: I found another picture of the pull-start side of the new trailer.

Man, that thing looks like a blast to ride. What are the old metal pieces sticking up on the rear wheel of the bike for?

 

[Jerryburger]

VERY COOL, ZnsaneRyder! Does the "pushing" upset cornering or anything like that?
I tried building a bike with a motor on the back, and the weight definitely affects handling. Plus you always gotta leanit on something because the kickstand is no longer effective. Could you plz take a close-up shot of where the hitch hooks to the seat post? Also... I'm thinking on disguising the trailer as an infant in a baby trailer! Think of it.... paint the motor flesh-tone, put a diaper over the fuel tank, find an old wig-head to glue on top.... have a small tape-player with an endless loop tape that has baby-sounds recorded on it!
"No officer, that's my little brother. He has excellent motor-skills for his age, doesn't he?" Ba-don-Keeesh!

They were where my original hitch was going to mount, I made it, but then I found the seatpost had better performance with balance and control, and re-made a new hitch for the seatpost.

Now those brackets are going to be for a rack-mount for a new engine on the bike in the future. I plan on getting a really small 4-stroke and mounting it on the bike, with a chain down to the rear wheel, and using the trailer on another bike. I'm still getting more materials.

Also, did the 12V/4V electrical system come with the engine?

 

[ZnsaneRyder]

The 12V/4V system is my own custom design. I have a switchbox on the handlebars that controls everything, 12V and 4V, and also including the engine kill-switch. The 4V Li-Ion battery is also inside the switchbox. The 12V battery mounts on the trailer.

The 12V is for automotive stuff, like my car horn, 12V taillight, and 55W Halogen headlight, and some 12V LED strings. Also the 12V battery charges the 4V system.

The 4V system is Lithium Ion. 3.7V nominal, 4.2V max. It runs my LED headlights, and LED taillights. It's a backup for when my 12V power runs out, I'll still have lights at night.

I've changed my setup some, and I'll have to post updates. My LED headlight is now a 4W panel of superbright LED's. It runs from my 4V battery. I'm not using the 12V 55W Halogen anymore, because the LED is almost as bright, and it shines further than the halogen, and lasts MUCH longer on batteries. I'm going to use the 12V, but it will just be for amber running lights, extra taillight, car horn, and charging up the 4V system.

I wish my engine had a charging system to charge my batteries. I just use a regular car battery charger to charge my bike every night I use the lights.

50mph? I've done that on some nice downhill road cycling, and it was insanely awesome. But having the motor push you that fast...on a mountain bike?
I salute you!

 

[BlueDistortions]

dude! very inventive! and i love that you used a dolly for V1! hahaha! major props!

 

[jr dragster T]

Is that a bottle of cheap alcohol I see in your kart?

 

[EagleTalons]

Looks like he is gonna make some fruity drinks.

Very cool !! I think you should plan a motorized wheel chair next with all the Goodies ,, Bill
