    Sachs 301 motorized wheel

    Saw a Sachs 301 motorized wheel for sale on my local Craigslist and made the deal for $100 Canadian. I also happen to have a bicycle frame laying around. After mounting the wheel on and cleaning the carb, it ran pretty well. Made a "stealth" gas tank from a breathalyzer calibration canister...

    Rubber mount

    Finally the weather is good enough to test the rubber mount build and glad to report that the mounts work really well. There is some vibration in the pedals but only at high speed, I can see the motor shaking around at part throttle but smooths out at load.There is almost no vibration at the...

    Rubber mount

    "SmokerX" the skate board bushings seems like a good idea, post pics. when it's set up. "Norman" it's been cold and we just got out of a Christmas snow storm, I tried to do some work in my garage,but only lasted one hour. A tuned pipe is on the horizon, but what is a " hood skin"?I modified a...

    Rubber mount

    "All dressed up and nowhere to go" Hi Neat Times, the great white north is a little bit frozen up right now , so no chance to fully test the mounts yet, will definitely update.The weak point is the small 6mm studs on the front slotted holes just like u thought, the rear mount has a small brace...

    The Pocket Bike Engine and Your Opinion...

    Hi Technocyclist, here are some pics. of a pocket bike motor, this one has the "big bore kit", there are mounting holes on the bottom. There are some pocket bike transmissions available, the one pictured has the clutch bell and 3.25:1 ratio so u would have to go 6:1 on the final drive to get a...

    The Pocket Bike Engine and Your Opinion...

    I've been playing around with pocket bike motor powered bicycle for a little while, check your local Craigslist for great bargains on broken pocket bikes, anywhere from free to $75. I got 2 free ones, one with good motor, one with scored cylinder but complete.I also got a water cooled one with a...

    Here's my next change. It's a 48.6cc pocket bike motor(44mm borex32 mm stroke) with a Chinese cloned ADA top end, piston and full circle crankshaft.They're very reasonably priced. This cylinder has twin boost ports making it a 4 port motor with 14:1 compression.The mainstream pocket bikes are...

    work in progress

    I decided to mount the exhaust lower, which requires re-welding and other mods. I tried a solid mount but after losing the header bolts and stripping out a hole during a ride, I went with a rubber grommet mount and safety wired exhaust bolts. I also decided not to use the Honda Passport front...

    Rubber mount

    Had a few issues with the muffler,the header pipe had to be lengthened and muffler braced to the motor to move with the motor.The chain was too short as the rear motor mount moved the motor more forward than stock.I had to find a #41 chain(only sold in 10' lengths) or a 415 chain, most bicycle...

    Rubber mount

    Thanks for the compliments, however this system is untested yet and I hope to test it this weekend.The one in the pics. are a one-off to fit on this Norco cruiser. If this works, then I will design a system which is much simpler and adjustable to fit different types of frames. I don't plan to...

    Rubber mount

    I finished the front motor mount today, I think I overbuilt the whole system, I probably could mount a small block Chevy in the bicycle. I hope this works, spent way too much time on this project.

    Rubber mount

    Just got one of China 66cc motors and looking at the flimsy stock mounts, I decided to make them better. At the same time, make them rubber mounted and adjustable side to side. This is what I came up with for now, I would've made the mounts out of aluminum but steel is more forgiving in the...

    Just bought a Bikebug

    Thanks Bikeguy Joe for the info, actually it did run briefly when I looked at before I bought it.I plan to go thru the fuel system and probably cut out the rusty part of the gas tank and solder a patch in.I'll bead blast the inside while the tank is opened up.

    Just bought a Bikebug from my local Craigslist for $75 including the bicycle, it seems to be complete.What u don't see in the photo I have in a box(muffler, gas tank, engine shroud ,roller shield). The gas tank has many pin hole leaks and quite rusty and needs replacement. A manual would be...

    Did some work on the gas tank mount and tried some ideas. I had this Keystone minibike gas tank from way back, it's a little scratched up, but it's a good looking piece and I didn't want to spoil the outline of it by strapping it down.I made a frame for the tank which fallows the bottom shape of...

    work in progress

    Update -decided to go for speed, for now, and mounted a 47cc pocket bike motor. I had to fabricate a new intake manifold since the motor is at a different angle and won't clear my motor mount. While I was at it , I decided to make the intake flange fit several types of carburetors. The flange...

    As luck would have it, I tried the Honda moped wheel in the swingarm and there was lots of room for the 2.50/17 tire. The wheel mounts on 4 points and not thru the axle, so by using the stock swingarm rear mount on the moped wheel upper mount and welding "L" sheet metal brackets on the swingarm...

    Here's my project, I found the "Jeep" mountain bike, the back wheel came from a Honda moped. The back wheel has a internal 12:1 reduction gearing with a disconnect lever and includes a drum brake. The clutch housing is a Stanton unit machined with two sets of mounting holes for a Honda GX31...
