Trials cranks will do what you want while not needing to cut off the spider.

Actually it's been a while since I looked at trials cranks and now I see that they are available in BB30 with a Shimano splined interface to a freewheel. That opens up a lot of interesting possibilities for various DIY mid-drives.

The Bafang BBSHD has been great for me plus there are all kinds of upgrades available from Luna, Grin Tech, and other companies. California Ebike carries every part in the motor should you ever need to replace anything and other companies carry the common stuff. Lekkie sells the motor sprockets from 28 teeth on up. Very simple to install with the only exposed gears being the sprocket on the motor that drives the chain...unlike some other kits like the Lightning Rod that has several exposed gears, chains, belts. BUT you are going to need more power if you are going to maintain speeds over 50 kph. With a high amperage controller you can easily maintain over 50 kph but the motor temps may be an issue...I don't know.

If I wanted to maintain more than 50 kph and use a mid drive, I'd go with one of the Lightning Rod kits.

A better and simpler choice for higher speeds is a Direct Drive motor.

My choices would be a mid drive for anything off road (because you can get the gearing you want/need), a MAC if you want to go less than 50 kph on pavement (higher acceleration per amp than any IGH or DD ebike motor), and a Direct Drive if you want to go over 50 kph on pavement (simple and won't over heat).

Yes it does have an internal gearbox reduction. Hills are no issue, especially if you shift the bike's gears appropriately.

CYC X1 Pro has a torque-sensing and has more power then a bafang.
It doesn't seem to have a gear box. Wonder how it would fare uphill. Also I notice a chain drive, these kinds are noisy and chain derailing can happen as well. I had a similar setup in the past it was very painful.

Thank you for posting the link. I was looking for something like that.
I build a medium power electric bike and now I'm working on 4-5 Kw version. It should be good for 45 - 50 mph.
The one on the photo is good for 30 mph and can climb a tree.

No sir! The motor is already in six bikes with 30 more in production. I will share more details when the time is right, very soon!

Our team is very hard at work ensuring this is the absolute best mid-drive ebike drivetrain available in North America, and testing against the best offerings from Bafang in particular. I have been absolutely blown away by the latest ride-testing experiences. Fierce performance particularly in steep grade climbing and rough terrain at high speed, without a single mechanical downtime. Maximum fun times, personally I've never had so much fun with fast, uninterrupted climbing, almost better than rapid descents!

Apologies, words will simply have to suffice until we're prepared to release information officially. This is not a personal venture and even if it were, I wouldn't be willing to spill the beans until bikes have been in reviewers hands and bikes/motors in stock to sell :wink:

Deafcat...how can we keep up with the latest info on the bikes you mentioned?

Depending on what they are and how they turn out, I may be interested in buying one.

Thanks

Just reserving judgement until I see what they have to offer.

If it's real and if it really has a torque sensor it might be worth a look.

That is not a mid-drive and probably weighs a ton.
But it looks fast so why not. :D

Why are you always so late that you need to go so fast?

I'll keep you guys posted here for news, we're making quick progress with the film work (marketing), and other things that need to be checked off before product reveal... It's been a very exciting couple of weeks for the whole team!

So a couple of weeks turn into a couple of months. Is it "soon" yet?
