Pinion E-Drive System: E-Bike Gearbox Motor

Pinion have crammed a motor into the gearbox. Here’s details of the Pinion E-Drive System AKA Pinion Motor.Gearbox.Unit (MGU). Pinion E-Drive TLDR: Pi …

Pinion E-Drive System: E-Bike Gearbox Motor

Game changer and start of the next generation of e-bikes.

I’m going to need one with the chainring on the opposite side*.

Jack shafts and high pivots FTW.

*How Dave Weagle managed to patent putting two chains on the same side I’ll never know.

Wow that must have been lots of development! Keen to see if it’s the gamechanger it seems it is!

Finally! MGU seems obvious, but taking some time to come to fruition.

That’s been a long while coming – was on their road map when they launched the P1/18. Lots to like about my old Pinion bike, the lack of weight on the rear wheel significantly improved the suspension action vs the same bike with conventional gears and the weight distribution felt great.

Certainly sounds like the obvious marrying up – any previous negatives of gearboxes (real or percived) largely negated by the electric motor.

That e-bike gearbox motor in a Nicolai/GeoMetron G1 please. Plus a lottery win.

Game changer and start of the next generation of e-bikes.

Agreed. And of course we will see trickle down tech.

Where are the ‘big players’ like SRAM and Shimano on a central gearbox?
Even smaller but bigger than Pinion, where companies like Mircroshift and Suntour?

That looks outstanding. Want one!

I was thinking more a Cotic Flare Max e-Pinion and a lottery win.
Plus of course a commuter / town bike. And another lottery win.

Hell. Yes.

As a pinion gearbox owner and lover, I’ve been looking forward to this coming out, so long as the cost isn’t extreme this will take off hugely.

Looks like a gamechanger but 4+kgs?!?!?

Do like the idea of it having electronic shifting though. Very smart.

This is awesome – what would be even cooler is if you could retro fit this system to your existing ebike. As you’ve already got mounts for a motor there, surely that can’t be an impossibility?

Assuming it works well, I think this will bring gearboxes to the mainstream

Cool to see, but what it says to me is: “Hold off another few years on getting an eeb, and see what else is in the pipeline in terms of engine/gearbox units.”

Can I ask a question to the eebers here?

These units come in 9 or 12-speed versions. How many ratios do you feel you actually need as a minimum? Could the motor assist mean you might get away with 7? 5? Even 3? Especially if the assist was engineered to respond variably to pedal input?

Hold off a few years and see what their reliability and warranty policy is like, would be my thinking.

This is where e-bikes have always needed to go. I’m waiting for the aggro DH/Gnarpoon versions.

The reasons I don’t have an e-bike yet are they they’re horribly overpriced, unacceptably unreliable, and they get slightly better every year.

By the time I want one they’ll hopefully be proper good.

Right then. This on a Nicolai please.

Hope this can be maintained and repaired rather than binned like Shimano.

Right then. This on a Nicolai please

I’m going to be following the Eurobike coverage to see who has one of these on a bike. Currently only seen brands I don’t recognise

there’s quite obviously a source of power from the big ol’ battery to allow for the electronic shifting

but will we see this be added as a feature to the regular accoustic pinion? might fancy a zerode if it is…

Looks like a gamechanger but 4+kgs?!?!?

A friend happens to have a bare E8000 motor in his garage and reports that it’s 3kg alone. Add in the rest of the drivechain and, as the article says, you’re at approximately the same weight.

My big question is long-term support from Pinion. I know a number of people with motors that have died outside of warranty and there’s nothing that can be done. Do Pinion have a track record of providing spares and servicing for more than two years?

IGH hubs are the norm in most european markets for the majority of bikes.  the UK is an outlier

Never sure of the etiquette of cross referencing another bike site, but anyway – interesting reading: https://www.pinkbike.com/news/first-ride-pinion-e-drive-system.html

Should be great if they can provide reliability and good warranties….

Cost will be interesting.

This is definitely the direction e-bikes should go in. Makes so much more sense

2.9kg and 2.6kg for of Bosch’s Performance Line CX and Shimano’s EP8 – plus another 1.8kg for a SRAM GX eagle drivetrain.

So at 4kg, it’s a actually lighter… Not to mention the advantages of reducing unsprung mass with no rear mech or cassette on the rear wheel.

My hunch is the service and warranty on something they make themselves in Germany will be A1. The Q might be about which parts are user-serviceable or replaceable, but with a customer base in durability-minded riders already I’d be amazed if they hadn’t designed this to take a chunk of market share by addressing the patchy rep or warranty concerns some other systems have.

Intradrive also working on something similar…

They should make one without the motor then we could convert old bikes to gearbox drive where the motor has broken

IGH hubs are for shopper bikes though. Not really the equivalent of a gearbox on a bike designed for schralping the gnarbar.

Unless you mount them in the middle and use them as the pivot point.

Yes, I’d expect mainland Europe service/ warranty will be excellent. Prob not so much here, I know you can get a Simplon in the UK – aren’t Merlin selling all their over stock at the moment? but pretty sure Rotwild and Bulls don’t have UK distribution. I’d expect any warranty issues to be extremely slow and laborious here unless they can get a really good distribution & dealer network set up.

I don’t give 2 shits about ebikes, but this is damn cool. All the downsides associated with gearboxes on regular bikes disappear when you slap a motor in there. Properly smart move by Pinion, I reckon. Hopefully the added complexity won’t compound with the astronomical failure rate of existing ebike motors.

*waits patiently for the electric shifting gubbins to be retrofitted to existing c1.12 gearboxes.

Piggy bank has a rather nervous look at the moment….

Looks like a great design that I’d love to have a go on.

Rotwild already have them displayed on their site but showing them with a chain rather than belt drive, which is a bit of a shame.

 

No mention of costs yet either

showing them with a chain rather than belt drive, which is a bit of a shame.

Rotwild are going with chains across all their pinion models apparently. Makes manufacturing and chain tension easier for one thing. Personally I’d go with a chain over a belt anyway.

This is a rather large step in the direction of emtb refinement IMO.

I’ve always wondered why ita not been done earlier – after all, the existing motors are all geared down internally anyway.

Who knows about the gates transmission stuff in the real world? Its clearly more expensive, but does it last any better than a traditional chain/sprocket system?

Belts.  Most folk find them longlasting and trouble free. @midlandtrailquestgraham destroyed them.   I opted for chain for easy repair.

I love the idea and it looks great. I’d question the range, who wants 600% gear range on an enduro MTB? 420% is perfect and covers very steep hills up to well over cut-off speed.

Me. It’s great for winching up stuff.
