I did my research on here and e-bay and such and found the best deal just down the street. 315.00 for a 9 continent 500 watt 36 volt front hub with 3 12 volt 12 amp hour SLA battery's. I installed on my Huge Hampton Cruiser all steel men's bike in less than an hour and was off on the charge that came in the battery's. on electric alone I am sure it is faster than 16mph at least at first, after a good hard 5 to 7 min burn some of the top end disappears. when peddling in 7th gear and throttle wide open I would guess well over 25 mph. I took it on a long haul today to walk and feed my friends dog and cat. about 8 miles total. I stayed on the sidewalk and made like I was peddling so as not to draw attention I just got in and my power says 60%. Tomorrow I will take it to the beach that trip will be over 10 miles, I can't wait to save up 250.00 for a LiPo pak, but until then I will have to deal with the weight. in 3 days I have put over 20 miles on my bike and my leg's don't hurt lol. I do believe I will need a new hub and bearings on the rear soon. I got roloff eyes on a K-Mark budget. I also bought a topeak rear rack to mount the battery bag, it was expensive but it has a U lock that slides in and out that is perfect for locking up the front wheel and I have a cable to lace thru the rest of the bike.
Thanks to Decon for all his post and all his help on previous gas conversions. When diesel goes back up over 5 dollars a gallon I got my electric bike. Jim....

I really am happy to hear about your bike. Sounds like you have a winner there. After having read about those new batteries and how close they claim they are to production, I have decided to go one more round with sla batteries. I am still pulling mine on trailers. I like the fact the bike itself is easier to handle with the batteries on a trailer.

If I ever go with a light weight battery, I might hang mine over the front bars in a basket. Keep the rear open for a basket of cokes or groceries. As long as the battery is light weight and centered on the front wheel it might be acceptable.

When I first got my set. I did not have a back rack, so I put my pak in my front basket, since my hub motor is on the front was way too much weight on the front, I am guessing even if the LiPo's are less than half the weight will still be too much. I like the battery pak on back rack and Pepsi in my front basket. I think when I get LiPo's I will mount 2 of them one on each side of my rear rack. do you Happen to know the Amp hr to weight ratio for SLA's and LiPo's what's the actual % weight diference? Also there are several types of LiPo's. what is the diffrence and long run problems. I am very happy with the hub motor and glad I bought new SLA's, rather than salvage. I was told to expect to replace the SLA's after 6 to 8 months.

It replacement is going to be harder than you think. Not the doing, the deciding when. My set goes back to when I first bought the first hub motor and even beyond. I should replace the oldest ones but they still charge. I'm sure they drain far too fast but throwing away something that still works is hard for me to do.

I just got a sla 12 ah battery in and the shipping weight was 9 pounds. I would think a set of three would run up about thirty pounds for 12ah. I am running a little more than 12 since I also run a set of 7ah in tandem with the 12ah batteries.

a 36v 15ah lipo4 battery is 5.6 kilos or about 12.4 pounds... A little than half the weight. That is very significant if carried on the bike but not so much if pulled along on a trailer. My motor is on the rear wheel and sitting on top so my light weight batteries in the front fork area might just be a good counter balance.

I think you made the right choice in the 500 watt hub motor. The 250 watt motor at 24v I have running 36v is just a little too small. I never use it now. I might give it some more thought later though. I wouldn't want to overpower that controller since it was a cheap one. The hub with 48v might be just barely enough to be fun to ride.

The drives I build are much better at 36volt one the 24v 500 watt controller.

I agree, I wanted a 36 volt 600 to 750 watt hub. but I settled on this one. since it's flat here except the draw bridges , I don't lose hard amps climbing hills.I have been watching and have seen most of the pic's you have posted. yours and my needs are very diffrent. I was at the bike shop yesterday and saw a confort bicycle, kinda chopper style it had a back post and was made to be riden leaning back or sitting up. I went BOING! 750 though, I thought about you, seemed like something you would like. I will try to get a pic of it sometime. Would be wonderful with a front hub motor and a small trailer for your battery's. My SLA's are **** on my rear tire and hub.

If they have a thrift store around there you can always pick up a five dollar child's bike and use the wheels to make a small trailer they are easy to make and make a big difference in how my bikes handle.

I got a wild hair and found my old front fork for the hub motor. I mounted it and will probably pick up a thrift store bike to stick the thing in. I have bike parts all over the place to piece it together with. I have been thinking I would like to give it another try just for the heck of it.
