After writing about this drill-powered bikes, I went to the norwegian 2nd hand marked Finn to find a manual scooter or kick-bike as we call it. The purpose was mod it to go electric. Luckily I came across one that was already electric, an imported, American Go-Ped Stealth. What I suddenly had under my feet was a solid skate board looking rubber tired vehicle.  I know nothing about electrical scooter so the refurbishment was on while the snow was melting on the streets.

It was supposed to run at 13 mph and for at least 30 minutes. The big battery that came on it was a heavy, 12V 12 Amp lead acid type. It lasted only for a few minutes at a slow speed, so I replaced it with 2 new 12V 7.2 Amps.

Two 12V 7.2 Amp and one 6 Volt 12 Amp lead acud battery under the board.

Also The spindle drive made the Stealth unusable on wet surfaces, due to a loss of grip between the engine and the tire. To avoid this I had to stick to dry pavement. With fresh 12V power the speed was still just around the 8mph / 13 km/h, so I tought why not try 24 volts? According the the technical info on the stealth, this is the correct current. I did a serial connection with the batteries to get the 24, and now the bike kicked some ass, until smoke came up from the rear. It was the heat fuse. It says 12V/30 Amps.

I Can't work out why this heat fuse is 12 Volts.

I’m confused. Does anyone know what’s the right current for the stealth? Am I possessing a Norwegian mod’ed version with extra limits for the legal rules? Anyway, what I ended up with was 18 volts.Two 12 volts in parallell, then serial with a 6 Volts 12 Amps. It runs pretty good but the heat fuse blows uphills.
