Need advice on good conversion.

Hello, i'm looking at convertion my Diamondback Response to an electric bicycle. I would perfer a rear drive, and i'm ok with a SLA battery. I'm looking at spending about $500 for the entire conversion, and would like 750w.

I am looking at the amped bikes setup, 385$ for everything but the battery, and then getting thier 12Ah 36volt SLA battery for 180$.

does this sound like a good deal? does anyone have any dealings with ???

hi i have had a kit on my bike for 6mths now. it was bought on ebay from hong kong for 205 with out batterys 1000 watt 48v great kit good and fast well recommended. as for sla batterys i bought 4x 12ah and found them to be okay for small trips about 7 8 miles max with peddling. i advise you to get 20ah can be bought of ebay for 92 deliverd. great range and bike will not get slugish. also you can add car spot lights without fear of batterys drainning to much. anyway its up to you but 20ah are heavier but more robust in the long run. hope it helps you cheers rob..

I LOVE my amped kit. Makes commuting SOOOO much better! I was nervous about a kit, because I frankly do ride my road bike at a pretty decent pace, but it honestly does make a huge difference. I went with a Ping 36v15ah and I've gone well over 25 miles, but I can't help but pedal. I could theoretically just use the throttle, but it just seems wrong. 700x40 tires and I'm usually cruising flats at about 23mph. With more effort, 25. Throttle maxes at about 30 going down hills, so I cut the motor and coast up to about 35. Like any motor conversion, it adds significant weight, but I can still pedal it if need be.

I bought my conversion for my bike from It's a rear drive 48V 1000W, cost $259. Also everything included but the battery. Then i bought a 12V 35AH on ebay and it goes well about 30 miles. For you maybe 20 ah is okey and i saw it on ebay it's usually not more than $100.
