What would you compare a mac on 16S 50 amp to ?

It pulls around 3500 watts. I have the phase set to 100 amps.

I never rode a scooter or motorbike so can't compare.

Thanks

There are racing 50cc engines that make over 3 times more power, and lame-ass 50cc engines that make 3x less power.

But I think you would find it similar to an average 50cc 2-stroke engine.

Do you mean a 50cc scooter or a 50 cc engine with the weight of a bicycle ?
 
I'm just talking power to power. Most 50cc scooters are way heavier and geared for high speeds, so they are slow as hell to accelerate, and your bicycle is likely much quicker.
 
Cool thanks.

I really hate the noise of scooters, the little 50cc things!

Yeah I would love to be stopped at lights beside a scooter and then hit the throttle, would be fun! :mrgreen:
 
holly smokes... 16s 50amp mac is surely a hot rod. At 1.5kw is abit slower than a 100c 4stroke moto wich has roughly the same power of a 50cc 2 stroke street moto/scooter (they are slowwwww).
With 3,5kw you ll beat a 200cc 4stroke for sure, but on the other hand a 50-60cc motocross 2stroke engine ll still kill you.

I saw you broke your MAC clutch bearing, my mac had the same problem and I was not able to repair it yet because of my stupid weak bones.
I was running my mac at 1,5 1,6kw input and based on a MXUS (9c alike) DD is no match even at 2.5kw input. If I was to get a DD motor to replace one geared hub that was running 3,5kw I would aim for 6kw input on the DD.
I somehow overdid it and ordered big motors from Hal/Accountant, and as soon as im healed i ll zap. :mrgreen:

Surely not? I used to own a 250CC bike - 29kilowats - 8 times the power at possibly only 4 times the weight. (More like 2.5x the weight if you count the 80kg rider).


That said, it was one of the higher powered 250cc 4 strokes, but if you're blowing off a 200cc bike with only 3.5KW, the motorcyclist can't be trying too hard.

Lol... I wouldnt say a 250cc 40hp is the standard for this size of bike. Most small street bikes have only one cylinder and dont rev high and at least where I live the 200cc ones have 15-17hp and im almost sure those hps were measured at motor, not at the wheel.
Even tho this was just a figure for Scorpion, I dont have a 3.5kw mac running, but my 1.5k-1.6kw one can play stop and go with 100cc motorcycles :)
Also, a 50-60cc motocross ll kill the 200cc regular 4stroke, because its geared for acel and not speed and not because it has more power.

That's still around 10-12kw, and the electric motor would be measured at the motor as well - or possibly even from the power used, rather than the power output.

Im gessing you never did anything eletric.
Let it be.

I have a 1000w electric. The thing is, the physics of it just doesn't make sense.

I had a friend who bought a 14.8 second Mitsubishi FTO. He dragged a 13 second Subaru WRX and won. He was bragging about it for weeks. It's questionable whether the WRX driver knew he was racing... Perhaps it is time to let it go.

Let it be, coz the 100cc im talking is one of my co-workers, so I know he was hauling.
curiosity but is your bike using a 1kw DD hub?

Ah - didn't see this bit earlier. Did you edit your post?

A 3.5kw electric motor makes 3.5Kw from the start. A 29kw motor makes about 2kw at idle.

So unless these bikes were actually revving up and dumping their clutch to race you, it's not a real fair comparison to say that you're keeping up with them. Sure, you're keeping up with a bike that might be using 20% of the available power.

Nope, i didnt edit the sentence. There was a post edit, because of typos that I saw after posting.
The eletric ll not put 80% of 3.5kw to the ground at 0rpm, but it ll put alot more power in the ground faster than the motorcycle, and being a geared hub, thats where it excel. The moto ll ultimately pass me, but it ll happen because of higher top speed and after gearing up.
Its not even close to a real race, as I said is more likely stop and go fun. If Scorpion was doing a DD, alot more power would be needed to have the same fun at traffic lights. But on the order side if the DD was big enough to take the heat it would still be working.

LOL! You got me remembering my red bike racing the scooter that night on the main drag in Jaco. My ebike had roughly 10 times the acceleration of that lame scooter, which was so slow it was funny.

Actually...the 3.5KW electric motor makes 0W at start, although it certainly might make a bundle of torque. ;)

The keyway popped out, but that might have been the way I re assembled it after replacing the halls that I blew by plugging the hall connector into the cycle analyst connector! :roll: Won't do that again! I was using a 6 pin jst connector, it's all I had at the time lol

It works perfectly now!

The mac is a seriously addictive motor I just don't want to get off of it, I have to hold on tight when I'm accelerating because it really pulls you back!

When I increased the phase to 100 amps the battery current stayed the same at around 3500 watts, but the acceleration was way better after turning the phase from around 50 amps! Strange the way it still pulled 3500 watts ?

49 wh/mile really drains my little 10ah pack. About 5.5 ah used after 6.5 miles of pure fun! :mrgreen:

That means my 16S 10ah pack has around 600 watt hrs, so I would get around 12 miles at 30-38 mph and that isn't bad in my opinion, not from a little LiPo pack. That's real efficiency and it even blows my Prius away!

To charge the pack costs only around 1.2 Euro cent, 1.2 cent for 12 miles is amazing.

I remember my Old Audi A4 diesel did around 600 miles on 60 Litres of Diesel or 15.85 U.S gallons at a cost of around 90 Euro's or 123 U.S.D (yeah you thought you had high fuel charges ? ) :D

SO if the mac can get me 12 miles at a cost of 1.2 cent per charge that's 600/12 = 50 charges to =600 miles

Then 50 charges x 1.2 cent = 60 cent LMFAO 60 cent compared to 90 Euros, is incredible!

I worked it out that on Night rate that it would cost around about 12 Euros in the Leaf to do 600 miles and that's worst case scenario where it might only get 70 miles per charge!

The Leaf II is supposed to have around 200 miles range and will be cheaper!

Well, true, no motion = no power, but you know what I mean. ICE engines have very little torque on idle, where as you can get full torque from idle on an electric. In fact, my controller boasts it has a "soft start" mechanism to avoid torque steer from stationary, and it still does that :p
 
Every time I used a 100cc gasoline powered vehicle I was disappointed in the performance. They are SLOW stock, and need some serious mods to be competitive with a 5+kW e-bike, aside from prolonged high speeds.

My slow commuter destroys my friends 50cc 2T dirtbike. Both off the line, and top speed, It's not even close. I'm thinking with a 5404 on 150V and 200A phase, it might be fairly quick.
