Best Hub Motor for Very Hilly Town?

[click68]

I live in a small (2,200) pop. town which is VERY hilly.I wonder what the best hub motor would be for hills?Speed is not important but 15 to 20 mph would be nice.Any suggestions/opinions/experience?

Team Hybrid puma or texas electric bikes hub motor.

Another option would be a Crystalyte 5305.

An economical solution is a golden motors hub motor. They are brushless and gearless, They are fairly torquey - not as powerful as the 5 series xlyte, but I find it a bit more powerful than a 4 series at 36 volts.

5305 in a 20" wheel will get you up any hill, batteries permitting of course. The 5304/20" is so torquey it will push my bike up overpass embankments, the only problem being that I couldn't actually stay on the bike for any length of time because the bike simply tipped over backwards.

To the original poster: How far do you need to go, and what percentage grades are you talking about? How much pedaling do you want to do?

Jonbear do you have one of these motors?

Are they the same as a GL2 here?

This looks like a great alternaitve to the X5 as the weight is only 15lbs.

The Puma is lighter at around 8 lb's, pulls like a train up hills too. http://www.armybikes.com/pumahubkits.htm

I live in Vancouver, BC where there are alot of hills, I prefer lightweight over a heavier bike, the puma or ezee motors look great from what I have been reading. The gl2 looks to be more powerful than the golden motor. From my experience the golden motor gives me more power than I need at 36v ( I need the exercise) - but people have different expectations of what is enough power from what you read here!

On my watt's up meter the motor can peak at 1800 watts (that is just the power from the battery), I do not know what exactly the motor sees. The controller is rated at 20 amps, but they run up to 40 amps with out modification, My crystalyte controller on the cycle analyst only occasionally goes above 20amps by less than 1 amp. The golden does reach 40 amps. I have 4 golden controllers (between me and a good friend actually) and all have different peak amp output. I don't know why that is. I guess quality control is not as high with these motors. However mine has worked great so far. So I guess it comes down to the size of your budget and how much power is enough. - A bit of a down side is that this motor is not compatible with the crystalyte controllers, so you are stuck with what you get. Also golden does not have great support. Hope this helps!

How hilly is very hilly?

Has anyone mentioned the super affordable 9C 2812? I have one on 20" wheel running on 52V. Top speed on flat is around 15mph and have no problem climbing 30% grade grass hill, no pedal assist. So much torque that it spun out of my front steel fork within a week of hard play (of course I didn't use a torque arm).

Hey guys anything against the BMC v2t motor. Mine runs great and I live in very hilly country. It also should be a bit more efficient than your Crystalite options. In truth I only have about a 150 miles on my setup, but so far so good.

[Kingfish]

Make mine a 2WD with 9C 2806 @ 63V

MHahaha! KF

[ohzee]

lol bumping a thread from 2008 where the OP has not been on the board since.

I wouldn't expect any responses from him.

Agreed!! I'm using BMC v2t now.
With 36V minor paddle to uphill.
At 48V you don't really need to paddle to up hill at all.
