Hi everybody,
I'm Jan from Belgium and I'm a 2-wheeled petrolhead, especially 2-strokes.
I love riding motorcycles as much as making/creating them. Currently I own a Kawasaki KR-1S streetfighter, and a KR-1S with a SV650 engine for streetuse, and a ZXR400 with a ZZR600 engine for trackdays. I'm also making a trackday KR-1S with a KX500 engine.
As for my profession : I'm a forklift mecanic.
Allthough I started my biking career on a trails bike, the first time I rode on fast streetbike I was completly adicted to it and switched. But I always told myself I'd get another trail bike, but somehow it never happened as I was too busy with my street/track bikes.
But since I started working for the forklift company some 4 years ago, I have learned a lot about electric motors/controllers/... and over the years, the idea of making an electric bike grew on me.
So now I posses a motor/controller/.... well, about everything from a working orderpicker that was going to be "scrap-metaled" (or however you call it in English). My idea is to make a trail bike with it, good enough to have some fun in the neighboorhood for 1 to a couple of hours - much will depend on how long the batteries will last. I can not see me having fun with an electric streetbike - nothing can beat a 2-stroke engine if it's about fun - but I see a major advantage in an electric streetbike : the noise it doesn't make and not bothering people with it in the neighbourhood
So here is my question : the motor I have is a Advanced DC Motors 140-07-4001 and a SEM-1 C 24V controller. The idea is to use it with 2 12V car batteries as big as I can get them in the bike (or 4 smaller ones).
This motor gives 2HP continous, 3HP for one hour and 10HP peak. max rpm is 5.000 ? but what can one expect from it ? what gearing to use ? I found a DIY bike with this engine (
http://www.evalbum.com/1415) and that seem's to be quite ok for my purpose: top speed isn't important, it "likes" 35mph which is ok I thinck on rough terrain, and it does about
30 miles which is enough.
Is my idea any good ? Does it make sense ? is that motor strong enough to ride up steep hills ? I found a graph on it's caracteristics, but frankly I don't understand it. The motor is supposed to make 5.000 rpm, but the graph only goes to about 3.000 ?
edit : forgot the link to the graph :
