Pro's/Con's of Ampedbikes.com kits

[IIIHorseman]

Looking for more detail was thinking about this kit:

All 36V Gear Kits Come With:

Double walled Aluminum rim w Heavy guage spokes complete with brushless Geared motor 350W-450W. 20 MPH (9 lbs)
Microprocessor controlled brushless speed controller 20A-25A max.
Spare Grips.
Brakes with motor cutoff switch.
Thumb Throttle with Battery indicator lights.
6 speed cluster (Rear Kits)
36 V 10AH Inframe mount (water bottle holes) lithium Tube Battery

This would go on a windsor dover 3.0 comfort bike with disc brakes.

 

[dougnutz]

A couple years ago when I was looking at those I was quickly advised to go for 48v since almost everyone that goes 36v soon wishes they had just a little more speed. They are nice kits but slow, which might be ok if you aren't worried about the speed.

Also the lighted throttles are reportedly problematic in the rain.

 

[ohzee]

I broke my teeth on amped kits and minus the lithium battery I thought it was a good deal for the money.
If you look you can find the same kits from cell_man for 50% cost (have to wait shipping from China) or
another vendor has a for sale thread in the sales section for like 100$ or more off what amped charges.

So even if you do go with them you can save more then from their web site.

I think their lithium batteries are overpriced - other then that it's a solid kit just suggest shopping around
if you want to save a bit. GL

ninjaedit: I see your buying a geared motor from them.. I also feel their geared motors are over priced. I never
figured out why , but if you compare them to some of the more reliable one's sold like MAC you can get a
better deal pretty easy.

assuming this bike has a min. 135mm dropouts it will do fine. the kit itself is solid, light, quiet, and plenty strong for most commuter applications. 36v in a 700c should put u at 21-23mph real world spd. if you jump to 48v i believe that will void your warranty (check first) but would not expect it to be an issue as david has done a fair amount of testing of these motors at that and higher voltages. that said, if you live in an exceptionally hilly area running at 48v would be preferred but also potentially problematic as things are going to get hot, 1 big hill not likely an issue, many hills? so, i'd suggest do some more reading to help you decide what application will best suit your needs.

this might help, i have a 26" kit in the forsale section w/ a brief vid which might give u a better idea of what you're looking to buy - im n europe so not trying to pimp my kit, just offering more info.

also as stated prior, cellman has a great product, has good CS and is noticeably cheaper but he's also along ways away and you can wait a min of several wks ($$$) to several months ($) depending on shipping so i would recommend you factor that into you equation as well.

good luck

Amped bikes kits and batteries are constantly out of stock and thinking about going with another vendor. What is a good alternative where the full kit price is similar to theirs?

 

[ohzee]

In the for sale new section there is someone who sells amped kits thru amped may have them in stock also cheaper.

ebikes.ca sells similar kits

It seems to me that amped lets so many different people resell their products they have a hard time keeping any for themselves.
just an observation though

cell_man also sells complete kits for a competitive price.

 

[The fingers]

Got the Amped kit but waited for a great sale price. I like it very much. It is the front DD/SLA kit but I upgraded the charger to a Sav-A Battery 36 volt and got a heavier rear rim and spokes because I broke a few on the old, non-stock rim I had installed years ago. Ten months of regular commuting 15-20 miles to two different jobs so far and loving it!

Does anyone know if the MXUS GEARED motor sold by AmpedBikes and HighTekBikes is a FASTER wind than the same motor offered by E-BikeKit and Cellman? Amped claims his geared motor does 20 mph in a 26" rim with a 36V battery but it that so?

-R

 

[IIIHorseman]

Yeah I was wondering the same thing. 17 MPH on a 36V is a bit too slow..

 

[NeezyDeezy]

I have one from hightekbikes, and 17mph on 36V sounds right. Definitely not more than 20mph.

The MXUS geared sold by Amped, Hightekbikes and Cell_man are all the same 250 rpm @36V motor. Motor merits aside, all three of these vendor's wheel build is excellent. The kit connectors vary, but I believe all three come with the tiny Shenzhen controller. There is reason to believe that the MXUS rear will fit a 135 m/m dropout with an 8 or 9-speed freewheel. A rider on the German Pedelecs forum claims to have done it. Also, Mwkeefer stated that he thought a 40 m/m free wheel would fit.
Ebike claims that their mini-motor is not a MXUS, although it sure looks like one to me. There was some sort of rowe here over this and I guess it got nasty. All the relavent threads have been deleted. Their kit is over-priced, so who cares.

I get 23 to 24 mph on 48V LI-on.
Flat
no wind
no pedal
250 lb. rider
dirt tires

So Russell, I guess you would top out around 50 mph :lol:

 

[neptronix]

The 250w cell_man kit i owned did about 18mph on 36v.. but that was RC lipo.. so no sag, and a bit higher continuous voltage versus something like regular ol' lifepo4 or some particularly wimpy NMC.

I think ampedbikes exaggerates their specs sometimes. But i'm not sure about this case.

I do recommend ordering from cell_man though. Same stuff, and run it on 48v if you want a bit higher speed.

 

[shock]

I've been happy with my DD amped bikes kit. Running on 12cell lipo does about 25. Controller will accept up to 60 volts stock. Dishing and lacing was much better than my ebikekit geared hub. Also all the wiring colors match up! Nice!

Terry is an excellent vendor.
Do read his thread in the sales section to see about free shipping in the states.

The reason I asked is I already owned a geared motor from E-BikeKit and it was a pretty slow wind. I really liked the motor and used it for something like 3,000 miles but it only spun unloaded at 335 RPM at 51.0V (236 RPM @ 36V nominal) meaning it was fairly slow (22.5 mph) even with 700Cx50mm tires on 16S LiFePO4 and around 18 mph on a 36V pack (42V max). I figured if the Amped geared kit could produce 20 mph with a 36V pack and 26" wheel it must be a faster wind and worth a try...but I guess Danny must be exaggerating things a bit. :|

Cell_man bench tested the MXUS a while back and got 255 rpm @ 39V.
That still doesn't definatively indicate that the Ebike/MXUS is the same or not. At any rate, they are very close
Running the MXUS on 14S LIpo might be mini-motor Nirvana[gear down, volt up as they say].
You remember this thread, where Mwkeefer tested the Ebike mini to destruction,

"E-BikeKit Geared Motor Special $200 Complete Kit"

http://endless-sphere.com/forums/viewtopic.php?f=31&t=18344

One of my fav. MXUS builds was,

Fredo's New Amped rear geared Specialized FSR !

He's got a nice Video in there as well.


Are you feeling the "need for speed"?

Yeah Cell_man's result is equal to 235 RPM at 36V nominal which is spot on what I got with the E-BikeKit geared motor (236 RPM).

If you scroll down a bit on that first link you'll see I snagged the dented rim special for $100.

Still it would be nice if one of vendors would offer a slightly faster wind that would actually do 20 mph in a 26" rim with a 36V battery.

[motomech]

They're out there.
This is from my post in the Geared Motors sticky,

"Here is a short list of geared mini-motor no-load[@36V] rpm numbers.
Not "chiseled in stone" and certainly not a definitive list, but I think they are accurate.
There is no difference between front and rear models where both "slow" and "fast" winds are offered.

MXUS[also called the Mini-might]
Only one wind offered- 250 rpm

Ananda[Cute] 36V/350W Q100 motor as listed on the BMS Battery site.
'201' "slow" wind- 230 rpm
"328" Fast" wind- 275 rpm

Bafang 3 Kg. motors, QSWXH, etc.
"201" "slow" wind- 201 rpm
"328" Fast" wind- 328 rpm"

I think the Ananda Q100 24/250W 328 is a fast wind, equal to the Bafang listed above[pretty much the same as your 24V GM mini, right?].

Only a serious pedaler like you would be interested in running a mini on 36V, just not enough reserve for hills and headwinds.

I'm running a "328 RPM" Bafang QSWXH now and it's fun on 12S LiPo (20A controller) though perhaps a bit too fast. I may buy a 36 volt battery for it and bump up the current to 25A to get the same low-end feel and about 23.5 mph top speed (700Cx40). I liked my MXUS geared motor (sold it) but it was a tad too slow on 12S (22.5 mph/700Cx50) and of course on 36V (18 mph) so I was just curious whether or not the motor AmpedBikes sells is somewhere in between...but I guess it's not.

[cruiserbikeman]

Pros: Direct Drive 750 watts, kit was carefully designed by a man (Danny) who is an ebike enthusiast and put his own money into starting his business, kit still running after 6 months.
Cons: Battery cost

 

[NeezyDeezy]

Actually, Danny at ampedbikes claims to have designed his direct drive motor, but it's really just a 9C, maybe with very minor modifications if anything.

 

[motomech]

Yeah, and Amped bikes claims to be offering the "3rd. Generation" gear motor kit....
It looks like the standard MXUS kit to me.
The fact is, he never designed anything.

 

[nicobie]

Hahahahaa...

Danny boi can't even tell the difference between 18 gauge and 16 gauge wires. His warranty lapses if you change out the shit molex connectors for something that will work @ 20 amps. Forget about troubleshooting unless you want to know about wood framing a house.

Other than that, he is a great guy.
