The Hydrostatic 2WD Raccoon is on the road, … um, make that on the trail. Jeff Parker finished the bike and took it out for a test ride which lasted for about 2 hours, it must work! The video even shows a few short moves in reverse. This looks like a fun and extremely practical project. Jeff plans to sell a video showing how it was built with a list of part numbers so you can build one yourself, most everything is off the shelf with a little modification. The video should be available in a couple of months.
Hydrostatic drive is looking very interesting and until I saw his first bike, I never gave it much thought. This is really cool!
Here’s what Jeff had to say:
Here are the basic specs,
Transmission -(CVT) Variable displacement piston pump
Fixed displacement hydraulic motors (1 in each wheel)
Wet Weight approx 270 pounds
Top speed 30mph
Wheels – 12 inch Geo Metro rims with front 4×4 ATV type tires.
When I first got it done, I think I drove it for about 2 hours. I couldn’t get off. It’s drives like nothing else I’ve ever driven. I expected the front wheel to feel like it’s pulling me around a little more but I really only feel it in the deep snow and climbing hills. The custom designed hydraulic manifold works perfectly. It gives me full time 2 wheel drive without bucking or binding ever. It’s so smooth. It took a little to get used to the high seat height but it is ergonomically perfect for me in the riding position. Being a hydraulic guy, I felt this was the only way to build this type of machine. The reliability of hydraulics is unmatchable. There are no chains, sprockets, jack-shafts, wheel or jack-shaft bearings, mechanical transmission, belts, pulleys, drive-shafts, u-joints, clutches, torque converter, external drum or disc brakes, and I’m sure I’m missing a few other things. This thing is so simple its amazing.
Nice job Jeff!
