Pinion E-Drive System: E-Bike Gearbox Motor

Would a belt limit the suspension design as it would be more diffficult to resolve chain growth/shrinkage with a tensioner as the shock moved through its stroke?

You can still use tensioner for a belt system.

Geometron / Nicolai used this on their pinion gearbox  G16. Someone local to me had one and I’m told the belt lasts ages and requires no looking after.

As do Zerode

Another reason to use a jack-shaft, I reckon.  Put the pivot wherever you want and keep the belt path simple.  Might need some sort of EBB at the pivot to correctly tension the Pinion to pivot belt which might be a bit complicated though…

Is this why Shimano have gone live with an auto shift ebike groupset, because they can not compete with this?

I’d take that range in a heartbeat.

I also have no interest in e bikes but this is a super cool development. The rear suspension must be buttery and one less thing to smash off of a rock. You would imagine much less servicing required, especially with a belt.

One step closer to a motorcross bikes…

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

Or wait for their warranty policy….

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.

I was watching the interview with Rob (rides eMTB) and they very specifically steer away … they pre-empted by saying “The thing most of your viewers will ask” and then started talking about weight not warranty!!!

They aren’t making the motor and he keeps mentioning 10’s of thousands of km… and though their existing customer base might be durability minded their new one is “disposable bike” minded.

He managers to slip in a few lies on maintenance as well… saying the only maintenance is an oil change “like suspension”… conveniently “forgetting” suspension also needs seals replaced.

Given this is a lot more complex and involves electronics and eggs in baskets I’d want to see spares and such available from them. It remains to be seen of they offer the same warranty as the gear boxes or less.

“To activate the 5-year warranty on your Pinion P-Line, register the gearbox on our website.

Proof of an annual oil change is a prerequisite for any warranty claims. Service is documented on the warranty card that accompanies the gearbox and is included in your user manual.”

@tomhoward a very long wait I think

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

SMART.SHIFT GEARBOX
Pinion Smart.Shift gearboxes differ from the P and C line gearboxes in their internal structure. The shifting mechanisms and sensor technology are the main differences. Smart.Shift gearboxes are based on the C-line and are marked with an „i“. (C1.12i, C1.9i, C1.6i).

As far as I’m aware there are no ‘service’ items on e bike motors – you run them until they break and then either get them fixed or replaced.

As an ex owner of a Pinion (and Rohloffs) the oil change is a simple cheap process. Seal replacement is likely to be a factory/distributor job but based on what I’ve seen that might be an 10 yearly job rather than annual. (there was someone on here who managed to wreck a few Rohloffs but that was repeated total immersion in deep water.

I reckon their gearbox tech (and sealing) is well proven. The unknowns are around the motor and electrical systems through the bike (eg I’ve seen specialized bikes have issues with water getting into the top tube display/controls)

2 years on the Pinion website.

@b33k34, if you follow their insta comments, and I do, there’s a lot of hinting that it’s coming in the future.

Whether they mean it’s a new GB with a stand-alone battery remains to be seen.

@chipps be a dear and probe them at eurobike? Pretty please 😊

Or wait for their warranty policy….

I think we all know that a company’s stated policy and what they provide in reality are often two very different things.  Just search ‘Giant warranty’ on this forum for some recent examples.

Saying that, this can go both ways and many companies will often go beyond their stated warranty policy.

Trouble is, you don’t know what it’s like until a couple of years after the first units have been sold.

In fairness, I’ve heard nothing but good things about pinions gearbox warranty. Lots of ‘it’s not covered by warranty but send it back and we’ll have a look’ only for a fully refurbished gearbox to be returned, FOC.

I must have missed that (or its new).
I can only find the gearbox warranty.
Seems like a gap between that and

The Pinion E-Drive System is therefore extremely durable whilst wear on the drive system is extremely low due to the elimination of external shifting components. The maintenance interval? A 10-minute oil-change after 10.000km. That’s it. Really.

Yeah, if they can combine a genuinely superior product with ‘above and beyond’ levels of support then they could end up cornering the entire market.

Edit: depending on the price, of course 🙂

I am confident they will exceed the low bar set by Giant but whilst I’m sure it will be mechanically sound the electronics and sensors are another thing. This is the main end-of-life in other eMTB motors (bearings and stuff can usually be sourced and changed … )

Even if they can survive financially if they end up with a high failure rate there is still the supply issue and not having a bike until its done. This pretty much seems to be what has caught out other motor manufacturers.

It seems to me like they are combining (in a sealed non serviceable box) the most reliable and least reliable things in MTB.

I still find it disturbing in the interview he doesn’t acknowledge proper (full) suspension servicing rather dismisses it as an oil change.

Imo ime fork seals only need to be changed when leaking ie repair.  I’ve never had any leak and have always just changed the oil in forks.

Multiple forks over many years with annual oil changes

I’ve got 4 sets of 2015 forks that have been mainly oil changes (technically 3 since last week when I gave a set away to a friend) and whilst I say “mainly” they have all been fully rebuilt once or twice.

I personally do mostly oil changes (warranty however requires sticking to the service schedule)… unless seals are damaged but the differences are

1/ it is because I can take the fork apart and actually check and not void my warranty AND
2/ I can buy service items (new seals).
3/ I can buy assemblies (from CSU to lowers to dampers) should it be damaged beyond the above
4) I can stick a fork on from ANY manufacturer into a “mount” (headset) that is standard. should damage be beyond the above

So whilst I’m confident pinion can make a long lasting gearbox… I’m far from confident about the electronics and sensors as no-one else has managed this in a MTB environment. When (not if) the motor fails you’re totally screwed short of buying a new motor (assuming you can). You can’t even as far as I can see keep using the gearbox unassisted … or rip the whole thing out and stick on a rear mech and shifters…

It’s a combination of the least and most reliable parts in MTB all stuck together in a non serviceable unit only directly replaceable with the same.

If your wondering how it rides around a carpark…

The auto shift seems to be great for commuters and shoppers, also love the auto shift to 4th gear when stopped. Remains to be seen how it’ll cope on a tech climb.

Nicolai released info on their Saturn 16 with Pinion MGU earlier – intriguing. Not really a looker but if it combines a motor, a gearbox and a Nicolai frame with decent (for me) geometry, then I don’t care what it looks like.

 

want!

“Not really a looker …..” ???

To me that is a fine looking bike. If it wasn’t going to cost the thick end of 10 (i’m m aking an educated guess!) then I would consider it for sure

It’s ugly but I trust Nicolai to make a bike that functions well so I’ll take one in plain black please.  Except the price, it’s going to be ‘ow much!!’ isn’t it.

As far as ebikes go, I think that looks pretty cool. As far as pricing goes (suggests €11,000 on facebook) I’ll never be able to buy one! Well, maybe I could afford it, but I just wouldn’t.

The top tube lining up with the seat stays helps it a lot… then you get to the headtube. OTOH the headtube looks a decent length so it might even get off the hook there too. Will gloss over having to re-mortgage the house to get one, otherwise I’d ride it

I was anticipating the common opinion on here of Nicolai’s looking a bit challenging, nto that I agree. I think it looks fine, as fdar as ebikes go.

Saw that Nicolai in a shop here in Italy the other week. Bugger me it was heavy!

Zero interest in e-MTBs, but fast Pinion motor would be great on a cargo bike like my Bullit.

I used to import Nicolai and have always loved the functional aesthetic but the seat tower on that is really fugly and the head tube isn’t much better.
