How does your ebike weight?

[Sacman]

I built my ebike as my daily commute vehicle. It had to meet following criteria:
1) Light enough to be able to pick up and load on and off of the train
2) Range of 15 miles with moderate pedaling
3) Able to climb 10% grades at sustained 15mph
4) Ability to hold 30lbs of groceries, laptop, change of clothes for office, food, ...etc.

Bike with Crystalyte 408 hubmotor = 25lbs
48v 15ah LiFePO4 Batteries & trunk bag = 21lbs
TOTAL WEIGHT = 46lbs

Top Speed: 24mph (on flat trerrain)
Range: 28 miles (full throttle with moderate pedaling)
Climbing Speed @ 10% grade: 16mph

Now with my 4th last battery pack and total of 2.2kWh it weight 130lbs.. and that probably saved me from a serious accident when i've hit a racoon last week!

The inertia helped me to keep control on the bike

 

[HAL9000v2.0]

0-60 kmh (~38mph)
6,2 sec (kelly 50A)
5,5 sec (lenze 66A)

top speed
72V 83 kmh (kelly 50A) (~52mph)
108V 112 kmh (lenze 66A) (~70mph)

-300lbs and 0-60kph in 5.5sec????????????? Are you serious?

-108V 112kph????????????????????????????

is it a motorcycle?? or an ebike?? if so.. do you use a 5303?

Doc

I use old X504.

 

[recumbent]

About 80 lbs all up, includes Shwalbe plus tires, pump, tool kit and pannier bag.

With a 190 lb rider, the front wheel on bathroom scale weighs 75 lbs.

Acceleration is faster than mini bikes, and faster than most cars at stop lights accelerating normally. But i pedal when i race

 

[powermed]

Since I dropped to 29v from 44 (Prius pack), the whole shebang is just under 45 pounds without the coffee. I shed another 3 pounds with the 10AH Headway pack I just bought from Chad for kicks.

Why all the hub motors? The key is using a through the gears drive and a 24" rear wheel - lots of torque, and in 8th gear, scary top end. Very fast and will absolutely pop a wheely in the wrong hands...

because a hub:

-Can handle 5kW+
-Can do the same or more torque and speed
-More efficient !!
-Less risk of breaking
-low width
.... and you have no gear sound

-and no risk of accident with fingers, chain, and gear!

!!!

because a hub:

Is easier to install IMO. For my mountain climb commute I gave very serious thought to a cyclone-style setup for torque, but was immediately turned off by the install procedures 'cause I got no install skillz. Hubbie slipped right into the dropouts, juiced up 84v and away I went zip zip up the hill. Easy peasy.

My trike weighs 45kilo including the motor...batteries another 25kg...so ~70kg give or take PLUS my 85kg self
perched on top of it... so ~150kg all up (thats 330 pound) Will drop by ~10kilo when i replace the lead with Lifepo4s..

"through - the - gears" does require a bit of common sense / trial and error, but c'mon, these forums are filled with people that do that everyday! If you look at the various pics on my site, other than the front freewheel and currie motor with planetary gearhead, weight claimps (could use U clamps instead), it's a couple of pieces of stock aluminum and scews from the hardware store...

Not a hub motor ride that's for sure, but that's ok if you like the smooth sound and power sounds of a brushless motor reving. Efficiency and power are way beyond any hub motor - in low gears and a 24v battery I can accelerate up almost any hill and overall I get a heck of a lot farther on a watt hour.

Its really pretty simple IMHO also...

Having a 10kilo hub motor hanging off the back of suspension arm does wonders for the ride i'm sure From what i have seen of the radial spoking of the large hub motors i wouldn't trust the wheel to not collapse with HEAVY off road treatment...

Not everyone has the batteries at their disposal like Doc to throw a million volts at a X5, if you throw 100volt at non hub motor it would fairly move too im sure. Fact is you dont need to to climb hills, my tired old slas gets my heavy trike up EXTREMELY steep hills As for fingers in the gears, what about the standard chain and sprockets :-S Why you would have your fingers in the vicinity in the first place i don't know, i know im not in the habit of riding around with my hands down around the rear wheel or bottom bracket are you Doc?

Each to their own though, dont let the instal put you off a non hub kit though thats a poor excuse as its pretty damn simple.

p.s also the changing of gears sounds pretty trick to hehehe

Fact is you dont need to to climb hill

Unfortunately I do need to climb hills as I work at a ski resort 1,600ft above the valley floor, which a 4011 @ 84v handled just fine. Can't wait to do it with my "new" old 504 rear @ 3kw. Plus in the woods deep I'd rather not have to work on a bunch of chains/gearing etc. etc. during a break down. With the simple hubbie I carry everything I need to fix any repair I can think of in the woods. So far, thankfully, it's only been spokes and flat tires.

As you say to each their own.

 

[vanilla ice]

Max gross has gotta be around 350 pounds for our tandem, makes me worry about the tires.

I wondered why all the hub motors too, bad for handling and sooo heavy. Then I installed one. Throw that bitch on there and go. The efficiency, quietness, thermal mass, blah blah etc, benefits I think pale in comparison to the ease of installation thing.

 

[Ypedal]

My ezee equipped bike, with 3ah lithium weighs in under 40 lbs 8) ( 30 something.. will weigh later )

The Chaos with 72v 20ah of lithium, rear 409 hub, dual crown forks, thickest tubes and tires i could get my hands on.. is rock solid and reliable.. 85 lbs.. on and off road. Handles just fine. I'm not a stunt man after all.. no need for perfect ballance and lightest weight possible.. that's not what i need.

I've installed a cyclone kit on a BikeE recumbent, i got it working good, not NEARLY as easy to install as a hub, sounds like a sick frog, and quite honestly is not any more efficient as the hub ( tested side by side with the Chaos, similar weight riders, etc.. )

Different strokes for different folks as usual.. all fun to ride either way !

l..now hook it up to 36v or 48 volts and see how it goes...84v you say...thats a difference of a thousand dollars of batteries (over a 48v pack) if Lifepo4s are used and bought from Australia... We have all seen docs climb a hill hes running a 100v FFS of course it will, your running 84 same deal...not everyone is going to pile a bicycle up with a ton of batteries to make it up a hill though are they Looking at 'ole Docs bike theres barely room on it for him hehehe

nice pics to Doc BTW

But yes each to their own, if you have thousands for a big hub and 80 odd volts of batteries so be it, for the cot of an x5 you can just about get a complete cyclone/battery setup...be interesting to see what all the hub motor users do when Matt has finished his RC reduction box and they are available, getting
your rear suspension 'weight free' again and dropping a ton of weight might be appealing to alot of hub users i think. I'm looking at
piling more weight on not less LoL..would reeeeally like to set up an etek on my trike along with a peerless diff...

Peace..

Haha... fun! This is like a Mac vs PC thread. :lol: :wink:

My batteries were $480US brand new and weighed 6.8kg. Hubbie was $280US. 84v5.2ah/~440wh... calculated to give me enough to get to the top of the mountain and another 3.2km on the way home after the decent. Worked very well... after all a watt/hr is a watt/hr no matter how you slice the voltage. You don't need 20ah at 84v and I think a lot of people forget how far an amp/hr can really take you. You do need good cells though . Batts all fit in the triangle. Very balanced. Total weight 29.5kg. Top speed 55kmh. Max grade around 22%. Avg grade 8-12%. Avg commute speed 25.7kmh.

Anyhoo... apples and oranges etc. etc.

HAHAHA yeah


.

Top speed 55kmh. Max grade around 22%. Avg grade 8-12%. Avg commute speed 25.7kmh.

Bit slow aint it 55km/hr pft my trike does 72km/hr and its using tired old slas

 

[pwbset]

my trike does 72km/hr

Yoikes. To be honest I almost crap my pants at 55kmh on the mountain bike. Too squirrelly. Been thinking lately that I really should have gotten a trike or tadpole to begin with... KMX... or something... so it's safer to ride in the winter... amongst other reasons. My commute is already socked in with snow/ice. I'm going through ebike withdrawal and it ain't pretty. :lol: :?

Understandable with that big heavy unbalanced hub motor bouncing the wheels around LoL...couldn't resist soz ;-P

Must be a pisser in winter with the snow and ice etc... i'll get to ride all year round here no snow just occasional showers in Winter and blistering cold days of 15 degrees...yes life is hard down here too ;-P

 

[pwbset]

yes life is hard down here too ;-P

Heard rumor that all Aussie sheilas are blonde and beautiful too... or maybe that's the east coast. Heh, heh.. back at ya! Couldn't resist! ;-P

BWAHAHAHAHA...They all look good after a 6 pack if not have a few more and they do LoL... There are ALOT of blondes here
Jurys out on whether they are all 'beautiful' though...

 

[DCM]

Bike - 82lbs (37kg)
Rider- 192lbs(87kg)
etc. - ~10lbs (5kg)

Nice looking bike DCM very nice...

I've never had the opportunity to weigh my rig.
But I figure it started life as a basic ~28 lbs mixte Cro-Mo MTB.
And to that add an Xtracycle and two thirds of an second roller chain, another ten pounds, roughly.
Now put on the fenders, lights, repair kit, lock, pump, passenger pegs. taller stem, wider bars, burgee cords, misc. plastic bags, larger tires and thicker inner tubes. . . maybe ten more pounds.
The batteries are listed as 15.48 lbs each so we'll call it 31#.
The 24.21 lbs 5304 rear motor and rim replaces about two pounds so let's count 22#
Now throw it back in for the controller, CA, cable, and throttle.
What have we got? 28+10+10+31+24= 103 pounds, give or take.

My weight fluctuates about 2.5 pounds around 145#.

So all up weight, without a passenger, groceries, shopping, salvage, parcels, gifts or carpentry/painting tools (and ladders) is 248 pounds or ~113 kilos.

The Xlyte monster has hauled that plus ~150# passenger up Main St. @ ~30 kmh. That's something I could never do without it.

I've found the Xtracycle to be a perfect accessory for carrying the required electric gear to move it expeditiously uphill with a heavy load.
The long wheelbase and mass means downhill speeds are limited only by your bicycle's brakes and your personal balls over brains quotient.

 

[Reid Welch]

My bare bike, as bought: the steel cruiser, weighted 22 pounds.

I will weight it all again after I finish the installation of battery and motor,
and put the final weight figure here.

The motor is the eZee front wheel motor. The total weight of that motor with my Bontrager tire installed is ten pounds.
Li Ping's 36V, 20Ah LiFePo4 battery pack and BMS weight 16 pounds.
I've added Planet Bike fenders (weight: nearly nothing)
And there will be a basket for the battery and Cycle Analysist, wiring, 20A controller, etc.
So it looks like the bike's final weight will be in the sub-60 pound range.
I weight 150 pounds. When my brain is empty, though my body weights: 2 pounds (jk).
The remainder of me is just so much shite :lol: Or, rather: an IQ of just 118. 8)

 

[Will]

This is my utility E-bike.

It's a lite 56.2 lbs :wink:
Add my 180lbs,
and up to $100 worth of groceries.
Love my E-bikes
