Yes, I have the 1680 Watt version. I bought the battery from ping batteries. The more amps you have the further distance you can go. To put it simple, more volts, more speed-more amps more miles. of course it has to do a little with the type of motor. My motor mounts to the frame where the newer versions mount to the crank arm. It says my motor will do 46 mph, I'm a big guy I can only get it to go 34mph which is fast enough.

I forgot to say about the wifes bike. It has a magic pie 3 motor with a 48 volt 10amp battery she can go about 27 mph for about 25 miles. At one time I put on my 48v 20amp battery and did the same speed but I got over 50 miles before recharge. I did have to peddle a little up hills but this is the quietest motor and very reliable.

You've been A TREMONDOUS help. Im sure Ive decided on the 1680 watt conversion and most likely a 20ah ping battery. Through my research I think the Sick Bike kit uses a Cyclone motor.

I weigh 163 (for the last 20 years lol) so I imagine my top speed would be a bit more. Getting excited now Im not sure if I want to use my Rockhopper or look for a full suspension bike.

I finally looked at Sick Bike Parts and Yes it's the exact same one I have from E-Cyclone. If I could justify it I would buy a 30 Amp battery next for even a longer ride. Good luck with your build. A full suspension bike would work great.

Ive been asking Paul aka Pablo a bunch of questions and think Im getting close to ordering.

Another question! So you have a 10ah ping for your wifes MagicPie 3. I think the 10ah only has like 20 continuous amps max and the MagicPie 3 requires like 30 or 35 continuous amps, how does this effect the battery and the hub?

I ask because the Sick Bikes motor requires 35 continuous amps but Id love to have the option of sticking a 10lb battery in my backpack for mountain biking on occasion and letting the wife use the 20ah battery and then when I want long rides to plug the 10ah battery back into her bike which is a front hub set up and plugging the 20ah back into my bike.

Best of both worlds possible here????

I do Have a 48v 10amp lifepo4 with 20 amps continuous. The wifes bike will run 27mph for about 25 miles. I have had no problems yet with this setup. I don't know the continuous output of my 20 amp battery but I know its more the 20. What you are talking about sounds like a good idea. Keep in touch.

35 amp continuous usually means the controller will support 35amps on a continuous basis, doesn't mean 35 amps are required constantly. My controller will allow 40amp bursts with 30 amps continuous. In the cruise mode Im usually only pulling around 9-10amps. You can certainly run the 10ah battery, its just a matter of how long.

I need to clarify some figures, was pulling them from my memory, not a good thing to do at my age. Had the specs from my battery mixed in with my speed control and the BMS. I have a 48v 15ah battery rated at 100amp bursts and 30amps continuous. My speed control is rated at 20amps max with 15amps continuous. The BMS is rated similar to the speed control. My system is relatively mild one, limited by the BMS/speed control basically. The motor in the SBP kit is a pretty hefty consumer/powerhouse. Im sure it will preform best with the recommended battery, but you could operate it on anything even SLAs with proper management. When you buy a battery see if it has a BMS and what the rating is, that can be a limiting factor even with a bigger battery.

Sounds like an interesting build. Have fun!

Jim from Sick Bikes e-mailed me and I will quote him.
I don't see an issue using the 10 ah battery as a back up. You can view batteries this way. The voltage is similar to the type of fuel and the ah is how large the fuel tank is. So a 48v and 20 ah is the same as a 48v 10 ah except 10 ah is only half the size of gas tank. So basically it will just run about half as long. Of course there are C rating and such but this is a good generalization.

Im still worried about overheating a 10ah battery if Im in the woods with hills and rocks and stuff but I guess that's what gears are for.

I better start ordering something soon with the anticipated long ship times lol!

Check out a web site bmsbattery.com for lifepo4 batteries. I bought my 48v 20amp from ping and I'm happy with it. They now sell for $658 with slow charger plus $31 more for a larger discharge amp rate and the BMS site sells theirs for $575 no charger and large amp discharge rate.
It all gets confusing...........

Thanks, that does save me some money although the shipping cost is a guessing game and you can even add extra money (a buck at a time) to cover added shipping cost. Odd.

I e-mailed the company and asked how that works, we shall see.

Any idea on which charger to buy???? Is it best to buy two?

Oh and Im not sure if I mentioned this before but the sick bike kit doesn't come with a 3 chainwheel option :( Jim at sick bikes will help me pick out parts to make it a 3 piece kit (although it sounds complicated) and they say 99% of the customers don't need that option. How do you feel about that?

A larger amp charger will charge faster. I have a 2 amp charger for my 10 amp batt and it seems to take forever to charge. And I have a 5 amp charger for the 20 amp batt and it's much faster. As far as the chainwheel goes, I find myself only using the 1 gear up front and using all the gears in back. If I had it all over to do again I would get the single chainwheel. Less shifting and less things to adjust.

Darnit lol. After literally hours of going back and forth I finally made up my mind on a vendor, BmsBattery. But then I looked around the web and found a lot of bum reviews along with good reviews. Downside is I'm looking at a 400 dollar difference between them and the next cheapest vendor Golden Motors which doesn't carry the 48v 12ah that I'm wanting (based on size) much less a 48v 12ah with a high rate bms.

Jumped into the deep end this morning and ordered two batteries from Golden Motor. I was swaying between Ping and GM and EM3EV and I think I was just over thinking over researching blah blah blah lol.

Have my eye on a Kona Stinky Full suspension bike but it weighs 40lbs!

Anyways, just updating the thread.
