Yeah, that's not an ebike anymore...

So how did you modify the motor for cooling?

It's still an eBike... just not a legal one... in most areas at least LOL

We're not talking about something that goes a few km/h faster then the limit... This vehicle goes 54.6mph, the pedals are not geared to be usable anywhere close to this speed, should be a pretty good hint right there... Now 54.6mph is 86km/h, this is full-blown motorcycle territory - even limited speed motorcycles are to top out at less then 70km/h, mopeds to 50-ish... And I know of no place on earth where this type of electric motorcycle, with pedals on it, would be thought of as an electric bicycle...

Despite your skewed conception of an electric motorcycle, this is still an eBike at the core but just way too fast, and illegal in most areas.

A true electric motorcycle can't be reversed into a legal eBike, Karma's bike can. As such... it's still an eBike, not an electric motorcycle.

You could build a bicycle out of stove pipe if you wanted to, but that wouldn't make it a stove... Imo a self-propelled, motorcycle-like device that goes at motorcycle speeds, should rightfully be called such...


Anyways I asked about cooling because I know of someone who fried such an MY1018 by overvolting it that way, running it hard for 7 miles I think. Ended up getting a new one & adding forced cooling. Good news is they're real cheap, 45$ at TNCscooters.

Well... that's just it: it's your oppinion and not how Transport Canada and the Ministry of Transportation sees it.

Karma's bike doesn't qualify as a moped, scooter or motorcycle. It's an eBike if he can keep it below 500W constant output at the motor and below 32km/h under assist power.

It's an illegal eBike but it's more closely related to an eBike than an Electric motorcycle according to the law.

Your oppinion has nothing to do with it.

PS: Motorcycles don't have operable pedals that can be used for propulsion.

It is unbelievable. Max 54.6mph (87 km/h) with 48V battery on an 24V brushed motor.
Is it on flat? Downhill?

What was the speed with 24V battery?

Lowell, what is your record?

56.5mph on flat ground, 62.5mph downhill. (Alex Fraser bridge heading south. Not sure what the gradient is)

Since then I've raised the nominal voltage from 91.2v to 98.6v, so if I run the 503/26" setup again the speeds will definitely be quicker. At 98.6v the 5304/20" combo has very good low and medium speed performance, reaching 40mph in 7 seconds flat.

got the izip to!!!

put it on 36volt since I read karma article on 48volt I got 50KPH on flat asphalt road and 45 kph on gravel W/o human help (I weight 175lbs) notice that the motor get fairly hot ! but use it full power only for burst when needed .

Karma have you done something to keep it a bit colder ?? also I notice that you put a front derailleur Which type is it ? how did you get it to hold there since the battery rack is in the way ? got a got close up picture by any chance??

btw karma do you use your izip @ 48volt daily ??

sorry for all those question but I would really like to do this to since it is basically impossible to help the motor @ 50 kph with the oem geared system !!

thanks !!

You are using 90V+ to get 56.5 mph.
Ampheno could do 50kpm using 36V (=> 41mph using 48V)
But Karma could get nearly the same speed (54.6mph) at half the battery voltage (48 v).

That is why Karma's speed is incredible !!?
Wonder if anyone else could get the same speed as Karma using 48V battery !?

This is a great thread, I have the same bike and it's a dog in stock form. I'm thinking of converting to the nano phosphate, A123 batteries a la dewalt power tools. That should be lot lighter than another SLA pair. yeah yeah, I know they cost their weight in gold.

Karma, keep the tips coming, I'm trying to do all the maintenance things you're doing on your bike. My bike with 200kms on it seem to be much lounder than when I bought it. I'm still a little scared to take the motor apart since you said not to take sides off or would have to totally dismantle.

I only get about 10 km/charge on it with stock batteries. Crappy tire never provided me with a charger, said they will phone me when they get one in, been near 3 months. I have to dismantle battery case each time to charge the sucker with a 1a 12v crappy tire trickle charger, ugh.

The ebike knew that you are upgrading to e-vespa and ran from you!

i have the ezip version guys what is the best way to boost my tourqe and speed just a little,should i go get a bigger motor say a 450 watt,or increase the voltage or both?i have currie setup 2oo watt brushed motor,lead acid battery 24 volts 10ah on my controller it says max ouput 25 amps output voltage 1-4 volts but this thing is sealed too so it looks like i cant tamper with that.any tips guys?

the currie motor can take a lot of voltage the izip is the same just add another 12volt battery in series to test
keep track how hot the motor and controller get. you may need to install the controller on the outside of the bike for cooling if its in a case.

hello !

I have been running my schwin i-zip wich is the same as the currie . on 36 volt for the pass 3 month .

36 volt cure the izip lack of torque and the motor and controller doesn't get hot . exept when I climb the hill @ my work wich is something like 18% for ~ 3km long all on gravel . then I simply get off my i-zip @ the bottom and wlk beside to save the motor and my legs no choice I guess only an gas scooter would do it .

other then that the only other problem I found is that @ full speed (36volt ) you simply have to pedal to fast to help the motor (missing a gear) so I don't use it full speed, until I put a front dérailleur like karma .

thanks for that guys so i can keep the same controller i take it just get another 12 volt battery then ok,i wont be needing full speed all the time just up a few little hills so i guess the motor wouldnt get too hot,like most things you just got to try one or two and see what works atleast your putting me in the right direction,big retail chains are going in big with these ebike here now and daily i get 10 or so folk asking me about mine,even the chicky babes haaaaa,they it.sydney has the worst public transport in the world i think its going backwards,petrol is getting to expensive about $1.50 per litre and folk really do want an alterative to cars.my bike beats the buses to the shops and its my main way off getting about now i do drive but not alot now i have the bike i see and chat to more chicky babes this way not jumping in the car again lol.
