No ill will is intended.
This is the most bang for your buck.

It is an internal combustion 2 stroke powered solution to climbing your 40 degree Paved slope.
A 56 tooth sprocket for the rear wheel.

Enjoy.
If you live in an apartment you must park 20 feet away from the building.
Lock it securely with three locks. No kidding .
I have had a motorized bicycle hacksawed in half when some one tried to steal it.
You are going to go through rims and tubes like you would not believe.
I had to go no mor flats .
Total cost is $183.99 from thats dax.

I am not concerned with going out it is coming back home that needs a lot of power.

I live in the cascade mountains.

Stevens Pass.

I live way out in the sticks. Gravel road, all the way to the highway, which is about three miles from my driveway. Then paved roads from there to town, which is another two or three miles.

The steep hills are on the gravel road. Steep hills both directions, but like you, the worst is on the way home. (That 40 degree slope is a switchback, three turns, and gravel, all the way...)

I don't want a lot of speed, or to run flat out... EXCEPT out there on the short stretch of highway, before the turnoff to go to town. That stretch of highway includes a narrow bridge. There've been a lot of accidents there.

As for the bridge... On the way to town, I suppose I could cross the highway just before the bridge, cross the bridge on the 'sidewalk', and then cross the highway again, to get on the 'legal' side of the road... That would necessarily limit my choices of build, to pretty much anything as narrow as myself and the bike...

As for the dax... I have a full suspension bike. I'd like to stick with this bike.

I don't see any options on the website, for getting the dax attached to a full suspension bike, like mine.

I suppose I could rig up some sort of mount system of my own. (I also suppose that even if I bought a kit, I'd be doing some custom work on the mount anyway. LOL It's in my nature. Hillbilly engineering, and all that...)

And if I am going to go that far, I'd probably go farther and use one of three chainsaw motors that I have, instead of ordering a kit... Then only have to buy a few parts. But like I said, I'd really prefer an electric build. (However, after seeing the cost of batteries...........Yowtch!)

~~~

Ok, at this point I am thinking that it makes sense to start my own thread.

Especially since I don't want to be hijacking someone else's thread.

But where to start it ? LOL

I have no idea, at this point, what kind of build I am going to end up with...

I do know that if I can't find anything suitable to my needs... I'll just keep the bike as it is, load it in the truck, and drive into town, to ride it around, there...

I built one like this for shopping with ease.

Luka, I have no knowledge about those cheap hub motors... but I do know "in general" that hub motors don't usually do very well on steep hills.

Torque is really about effective gear ratio... with the hub motors they get their low rpms by using more magnet poles in the design and that lowers the rpm, but you have to use more weight to get more power. Some of the better quality "Big Iron" hub motors that could actually get you up a steep hill weigh in the 25 lbs range. That's 25 lbs that is going to smash into rocks with your rims while your 280 lbs will add to the stress. Your rims will become pretzels in no time.

Using geardowns and an independent motor allows you to start with very high rpms and then ultimately get the torque you want at low speed.

Let's do the math:

Motor Rpm - 4000

Geardown - 40 to 1

Resulting Shaft Speed - 100 rpm

...now that's a key number because 100 rpm is considered the maximum speed of a person pedaling a bike.

The "bottom line" is that you need about a 40 to 1 geardown to make a good hill climber bike. How you do that is the question... and I have no easy answer for you. Ebikes are not really very sophisticated yet, most of the cheap ones just stick a little 450 watt motor onto a bicycle and using direct drive they gear it to run about 20 mph. Going up hill you need a gear that will work optimally at about 5 mph.

I really have no good answer for you...

The Cyclone might be your best bet. It attaches to your chain so you get the full range of your bikes existing gearing. That way when you are in "granny gears" the motor is being useful.

...however, it's going to set you back half a grand just to get started with these kits and that's not including batteries. Pretty soon you are into it for a thousand dollars.

What seems to be happening is that there is an "outlaw element" that is dominating the internet where all these ebikes are being modified so that are way, way, way past legal. (it started with "Big Iron" and has now shifted to RC motors, but the problem is the same)

Your so full of s h i t safe (but that we already new) there is a hand full of people using rc setups you know very well the ebike scene is DOMINATED by LEGAL size hub motors but as usual you come into a thread take it right off topic im surprised you haven't bought up your ebike racing bull s h i t nobody wants too hear, the thread is for SUPPLIERs of inexpensive parts

Luka...dpending on your level of skills a either a geared hub motor or a bolt on cyclone kit would do you fine ...The hub motors for hill climbing need to be geared OR highly volted (72 plus volts) to match a well geared Cyclone and even then the cyclone IMO is a better choice THAT SAID though, the cycleone kits do need some updrading to be reliable, the freewheel they come with is well...rubbish, should be replaced by the White Industries HD ENO (sick bike parts sell a specially made replacement) You will also need some basic tools and a little mechanical knowledge to fit the system to your bike...There is a good tutorial on the Cyclone site showing how to fit the kits. The hub motor is alot easier to instal and is one of the reasons alot favour them, they are also alot quieter having minimal chain noise but as mentioned if you have hills to climb you will need a geared hub motor OR a non hub running THROUGH your bikes standard gearing...I have upped a video on Youtube of my mates Cyclon cruiser climbing a VERY steep hill might want to check this out and decide for yourself if this is the better otpion..Link To Video This is a Cyclone 1000wat kit running on 48volts with a 3 speed hub. I would recommend checking the offerings of http://www.ebikes.ca/store/store_ezee.php if you buy a hub motor they offer VERY high quality kits and superb custom support THEY ARE however pricey do to this. Ebay is also a cheaper option for hub motors i have seen 1000watt kits for under 300 bucks (minus batteries) http://www.electricrider.com/crystalyte/parts.htm <--this crowd also do a cheaper setup the Crystalite which is pretty popular from what i have seen. So theres a few alternatives for you to think about, decide how much your willing to spend as this is what will gauge the setup you will eventually have... best of luck i hope this has been of some help.

Anyone looking for good prices on NiCd or NiMH batteries and chargers All-Battery Center is a good place
http://stores.shop.ebay.ca/All-Battery-Center__W0QQ_armrsZ1

Sorry if any of these have been mentioned already

Monster scooters (which has already been mentioned) has alot of parts but for those outside the US (i'm in canada) watch out for high customs prices.
The 600W GEARED Motor - 36 Volts (Style: MY1020Z3) cost me an extra $55 for customs) when it was delivered.

New to electric bikes

I don't know all the latest parts and brands etc, and was interested in something homebrew style.

I was wondering if 2 12v Deep cycle car/marine batteries and an inverter could power a vacuum cleaner motor or baldor type motor and run a bike with a v belt drive system.

 

[professor]

Happy- no problem getting those components to operate but a 200 pound bike would be a lot to move around, stopping might me an issue too.

 

[happycheapskate]

Thanks for the info.

I guess if I attempt it, I will mount the batteries/battery beside the back wheel which seems to be a popular approach, and I will use good quality v brakes. I would expect handling like an industrial cart and plan to use it mainly to chill out downtown or go to work on (less than 10 miles a day).

I don't really need an ebike right now, and I think most of the commercially available ones are unnatractive and impractical as well as very expensive. The concept of e bikes is good though. I think the home assembled type are more interesting. The price and reliability are more important to me than speed or high tech parts.

I already build my own wheels so that wouldn't be a problem, even re dishing or re spacing wheel axles is not hard.

Good thread.

I love my Grubee!
