New to the forum. Few questions.

Hey so I'm Nick and I'm new here. I'm deciding on getting an ebike as I dont have a drivers license and looking to commute to work (I'm an electrician)
I live in NB Canada and we have some pretty nasty roads in the Winter so I was deciding on a fatbike.
I want something that will go faster than 32km/h when using it off road (preferably around 60km/h top speed.
I also want to put a cap of nothing more than $3000. I found some good options with luna cycle and hpc but the issue is that their pre built bikes that I was interested in are sold out and also that the exchange rate from canada to us dollars is high and added with shipping it would cost over an additional $1000 at least.
I'm wondering if there's any canadian companies similar to luna cycle or hpc or my second option would be to build it my self (buy a fatbike and the parts needed from luna cycle) although I'm worried that I'll mess it up.
Thoughts?

They're very well known in both USA and Canada for developing the Satiator charger, Phaserunner controller and GMAC motor.

Here's useful tool.

Thank you for the info.
I was thinking about getting a geared (maybe 7 speed) fat bike and then getting a mid drive motor for steep uphills in the city. I was thinking the cyclone https://lunacycle.com/cyclone-mid-drive-3000w-planetary-kit/ paired with a good 72v lithium battery https://m.ca.dhgate.com/product/72v-18ah-3000w-electric-bike-battery-72v/422798648.html?f=bm|GMC|pla|1660931651|62956754854|422798648|pla-296557785071|103006001|CA|liuzedongkkkk|m|2|#pd-103

But now looking at the info you sent I see the GMAC motor is a geared hub? Does that mean it could work with switching between gears on a 7 speed despite it not being a mid drive? Also would I have the ability to switch between pedal assist and just strictly throttle? Lately if the battery does die can I see bike normally to get home?
Thanks again.

I am not all that familiar with GMAC, as I have no personal experience with it.

But do you know Juiced Hyperfat? One that came with the MAC motor?

The Juiced Hyperfat can go 40mph (64km/h) with the MAC motor, and it wasn't even pushing its limit.

The GMAC is evolutionary model of MAC motor mad by Grin, so it's better.
I believe despite being a geared hub motor, it comes with re-gen brake, which traditionally was only for direct drive hub.

With a speed controller such as Grin Phaserunner, I bet the GMAC can really go fast, but I am not a Grin product adviser so I don't know..

Please show me some evidence of that. Which MAC motor wind?

If you use the tool, you posted, you'll see how this is not possible!

To the OP...

In order to hit 40MPH you'd need a 35A controller, a 72V battery, and you'd overheat in under 20 minutes.

GMAC with 72V will squeak out 35MPH but may have heat issues too.

getting to 40MPH is a wall for most kits. Stealth eBikes with 3000W plus hub drives in motorcycle rims or ramped up Cyclones will get you there.

BUT this forum is hardly the right place to learn. See endless_sphere.com or Luna's forum for help that won't provide the misinformation already delivered here.

I think the OP needs a motorcycle, you can't safely ride a bike at those speeds on "bad roads".

On second though, I put away my motorcycles every winter, two wheels and snow, slush, and ice don't mix. it's one thing to go out and play in the snow with fat tires but commuting?

Really? Ebike commuting is a thing all winter long in New Brunswick? A fat bike will do no better than a mid size tire with studs, probably worse. When streets are frozen, the fat tire will be worse as it "hunts" from rut to rut. You have read that battery range drops dramatically in the cold, right? It took me 9 months to heal from a crash on ice with my fat bike that happened last January.

I didn't feel the need to mention that I would not be driving it at 60kmh during winter months, felt that was self explanatory. I would drive it at low speeds on crappy roads as does everyone driving a car..

But as mentioned, riding at 60kmh is a pretty big challenge for an assisted bicycle any time of the year. The human body is quite an aerodynamic brick wall and it really takes the energy over 35kmh. I ride a lot at 35kmh, but you dramatically drop the range when you get over 45kmh.

This fella is doing 40mph with a cyclone 3000 motor and 72v 24ah battery and he did 15 miles with 60% battery life remaining. The average commute to work certainly wouldnt be any more than 15 miles tops and I could always charge it at work

I would say that one of the quickest way to achieve 40mph is by looking at something that's capable of 40mph and study their specs.

MAC motor and Bafang Ultra are both worth looking into.

Juiced Hyperfat was one of them, also have you ever heard of FLX Blade? With Bafang Ultra, it can go up to 40mph.


There are tons of YouTube videos as you probably already know. I think videos are worth thousand words.

I thought you said earlier that $3000 was your cap?

Timpo, you are a great fella who goes out of his way to be helpful, but so often you share your Google experience. Pretty good copy and link pastes. But more often than not anecdotes and zero experience. Continuing to post Ebikes.ca links and advising readers to use their motor spec calculators but when we do your claims are oblivious of the simulation FACTS.

neither motor is 40mph capable . Period.

maybe we should share our direct experience not regurgitate opinions. Perhaps helping new fellas with misinformation is not really useful and perhaps even dangerous?

50mph if he wants...but only with a product best suited for advanced users, pushing sketchy safety limits

i have an acquaintance that runs his major upgrade cyclone on a recumbent. Very capable of 40mph. JohnCR on ES perhaps one of the best high speed “eBike “ builders

i went a few weeks just not reading your posts and responding. It’s probably viewed as being a dick most often correcting you, but in my option it’s best to not comment if you’re going to continue with the anecdotes.

I built one crazy fast 2WD MAC. Just because I could but it was a dangerous bike. I didn’t commit to keeping the build as the cost of making it a safe bike was quite a high cost. Damn it was fun, until I needed to stop.

Again your advised link clearly demonstrates those two motors are not capable of 40mph.

a $700 Crystalyte The Crown motor will do 41mph 100% throttle Statoraide and cooling fins could push that but not at cyclone prices.
