Just finished working on my electrified bike. It’s built around a 1930 Schwinn frame with a with a Schwinn approved four rail spring seat from the 50’s. I build a rear rack out of an old four foot level that had lost its bubbles, an aluminum serving tray, scrap aluminum sheeting left over from the “Dogtown Too”, and an old laundry basket from when I was a lifeguard thirty years ago. Under the rack are two UB12120 sealed lead batteries that go with two more sealed lead batteries carried in the frame. The batteries are wired in series giving the
Crystalite Roadrunner front drive wheel 48V to deal with. I rebuilt an old expanding shoe tandem hub for the rear wheel and attached a derailleur to use the Suntour 5 speed cluster I had in the junk bike parts box and fitter a Suntour derailleur and hanger from the same junk parts box. I drilled out the front fork and put a cheap side pull brake on the front power wheel.
The bike is fitted with 26 inch balloon tires (semi mountain bike tread) and has been fitted with chrome fenders front and rear. Between the twin top tubes I fitted a wood tank (like an old Schwinn Phantom) with a graphic that says Chicago Iron. The bike has wide bars (like a Fatboy) and a pair of the cheapest steep brake levers I had in the junk box.
When I finished my creation about 6:00 PM this evening I took it out for a test ride and even though it weighs a ton (about 75 pounds considering the batteries-25 pounds, the front wheel-20 pounds, the Chicago Iron frame 30 pounds) it screams—about 25 mph on the flats with no pedaling---. On my test run I met up with a young cyclist in full racing regalia on a roadbike with clipless pedals who struggled to try to leave me (an overweight senior) wearing a pair of cut offs, a tee shirt, and loafers--- Finally on a slight downhill grade—he hit his big wheel (probably 126 inches) and he pulled away—I figure I was doing 35 mph and I’d guess he was doing 40. Nevertheless, I don’t think he realized I had a three to five hundred watt very quiet turbo. On the way home I stopped by a local biker bar for a beer and parked the Chicago Iron beast in line with the Harleys and wanna be a Harleys. A couple of the bikers who know I normally ride a beemer complemented me on finally riding an American Bike---unfortunately they are only partially right as only the frame and seat are American---and the front drive wheel is Chinese.
After my beer on the hill climb home I was able to stay in the seat without breaking much of a sweat. All in all a 10 mile ride—the batteries lasted pretty good considering they were new and I hadn’t topped off the charge (they are being recharged as I’m writing this.) Tomorrow is another day and after checking it beast over for loosened nuts and bolts I'm gonna take a longer ride with fully charged batteries---I figure their range is 20 to 25 miles if I don’t get too crazy, possible 30 if I pedal a little.
All in all I figure it a viable form of transportation for quick errands around the house and camp. One that uses electricity instead of gasoline---a good economic stimulus.
I’ll post some pictures as soon as I find the missing pixels.
