Did you go with front or rear?

I know it's too late, but I'd like to recommend a rear kit for the hills. Not for going up the hills, but down. I can't express how much more comfortable it makes me feel bombing down a steep hill with a bike that is more heavy in the rear than the front. With a front hub kit, I'd imagine that it might be possible to tap the front brakes and have the back wheel come off the ground on a steep downhill. My bike used to do that pre-ebike kit and it was nerve wracking. That is pretty much impossible now with my rear hub setup.

I've never had a traction issue with a rear hub. Too much weight on that tire already.

Re fastedddy

Some of the older versions of lipoly batteries could catch fire, especially when charging. The lifepo4 never had that problem, and was adopted by many for that reason. Pingbattery, headways, etc are all lifepo4. Though more important for lithium packs, all batteries need balancing to work properly once you string a bunch of cells together for a higher voltage pack. Even the lead batteries in electric cars work better with a balancer.

The bms that comes with the battery is what does this for you in a lifepo4 pack. As long as you have no defects, runt cells, or bad connections in a pack, balancing is just a matter of plugging in the proper charger, and leaving it plugged in for awhile after the pack is charged. If a cell is not fully charged, the bms senses this, and will turn on the charger again, cycling till all the cells are fully charged. Some will tell me that isn't exactly how it works, but all we need to know is leave it on the charger long enough and somehow the bms and the charger get it done for us.

If you go to the battery section, it can get pretty overwhelming trying to understand it, and you might get the idea that there are allways problems. Not really the case, but some ebay sellers have sent some junk out. Pingbattery has a good reputation, and the headway cells are proven to be high quality. There are others with good stuff, but the list gets kinda long. Ping and EV components for the headways are the best quality for the price most of the time.

I'm not electrically inclined but I do know bikes a little. Probably 180 mm Avid rear disc brakes would be best. I only use mechanical brakes but they make some really nice hydraulic brakes also. This is where I usually buy my parts. They have a large selection and you can call and talk to someone who actually rides a bikehttp://jensonusa.com. I only say Avid because they have a pretty good track record. I'm only using 160mm discs but I'm only running 500 Watts on a 80lb. bike and I only weigh 145lbs.
And please,please,please post pics. and performance info. because I'm seriously considering the BMC-V2T myself. I live in hill country also.

Thanks dogman.
I'll call ebikes.ca since they are 35 miles north of us and then Ping for the battery.
I'll probably hate myself for it but when the fellas on the other bike sites are worrying about the cops grabbing them and thier bikes I will take fiendish joy in pointing out that if they had gone electric they would be safe.

Saw your thread on hot air ballons. You Sir, are a brave man in my books. Not only do you hang in a basket under a sack of hot air, you have the rocks to bear up under the cost.

Thank you,

Steve.

I'm using the little rubber wheel rim brakes...I smoked through the ones that came with the bike doing speed tests with a 48v SLA array on a rather tight oval running track. I think the ones I have now are just cheap Bell Oval pads which were 2ea. for $4.95 at WalMart. Some people smoke through a set every 1-2 weeks...I have had these for about a month and there is still pad left. There is no clearance between the hub and the forks for installing a disc brakes on a 9c motor on the front wheel...people have only done it on the rears as far as I know....you might be able to add a rear rotor to your normal wheel....or buy a rear set with a rotor mounted.

If you went with the BMC...there may be a side cover you can buy with disc brake mounts...in fact I think the ladies you're already dealing with can hook ya up!

From Cycle9's website describing the BMC V2-T conversion kit:

• Disc-brake compatible, 6-bolt disc mount on left side
