The ‘S’ suffixed motors are Speed Pedelecs

Pinion press release in full:

WORLD’S FIRST. MOTOR AND GEARBOX. FINALLY UNITED.

The drivetrain is the heart of an e-bike. Until now, this has consisted of two separate systems – a gearshift and a motor, which usually come from different manufacturers and yet somehow have to work together. The consequences are bad shifting performance, high wear, followed by high maintenance with enormous costs. The Pinion Motor.Gearbox.Unit (MGU) is here to change that.

Pinion brings together what belongs together. The Pinion MGU is the e-bike technology of the next generation – because it combines motor and gearshift into one unit. It combines a powerful electric motor with proven Pinion gearbox technology and electric shifting of up to 12 gears in a compact package to create a completely new drive system for e-bikes. Motor and gearbox are optimally matched and work together like never before. Pinion motor-gearbox units offer durable shifting and motor performance at the highest level. Designed to work worry-free and reliably, with no significant wear and minimal maintenance. One oil change every 10,000 km! That’s it!

As a world first, the Pinion E-Drive System with its core Motor.Gearbox.Unit (MGU) will be presented to the public for the first time at Eurobike 2023. The following launch partner brands are offering e-bikes with the Pinion E-Drive System in various categories for the 2024 model year: Rotwild, Simplon and Bulls are launching unique E-MTBs with perfectly balanced weight distribution and impressive performance. Kettler, Flyer, Tout Terrain, Pegasus, Zemo and I:SY will offer e-trekking bikes, e- cargo bikes as well as e-compact bikes. Speed pedelecs with Pinion E-LINES series MGUs are in the lineup of various brands

THE HEART OF THE SYSTEM – THE PINION MGU

The Pinion MGU combines a wear-free electric motor and the innovative Pinion gearbox with 9 or 12 gears in a compact all- in-one package of comparable size and weight to current mid-mounted motors with separate gear shifting. Controlled by electric shifting and powered by Pinion’s own hardware and software, the Pinion MGU is the heart of a completely new drive system for e-bikes.

The internal development of all integrated electronic components is the key to ensuring that all parts of the system work together as one unit to deliver lightning-fast, crisp shifting in all situations and on all terrain. The Pinion MGU operates reliably over the long term with no significant wear. The MGU is located centrally and low in the bottom bracket area, resulting in optimal weight distribution of the e-bike. The elimination of the external rear derailleur and cassette is also accompanied by drastically reduced maintenance. An MGU and its integrated shifting technology operates virtually wear-free and requires nothing more than an oil change every 10,000 kilometers. In addition, the system significantly reduces the unsprung mass at the rear wheel, which results in better suspension performance and ultimately leads to greater comfort and traction.

The roots of the motor inside the Pinion MGU is a state-of-the-art e-machine for industrial applications, manufactured in Germany and redesigned for use in an e-bike. The motor offers extremely high efficiency and a highly dynamic power density without sacrificing shifting performance.

All MGU versions are based on 48 volt technology and offer approximately 85 Nm of torque compared to conventional motors without integrated gearbox. However, due to the integrated gearbox, the output shaft values are not directly comparable with those of ordinary mid-motors. In the first four gears, the MGU delivers up to 160 Nm of torque to the rear wheel. The peak power is 600 watts, and 800 watts for the S-pedelec versions. The maximum support is up to 400%, and that at a permissible input torque of up to 250 Nm.

Thanks to its operational design, a Pinion gearbox offers more reliable shifting than conventional bicycle derailleurs and is far better equipped to handle the high loads imposed by an e-bike motor. Proven for more than a decade and used by over 100 bicycle manufacturers, the technology is reliable, durable and needs extremely low maintenance. There is no rear derailleur that can get out of line or break off. In addition, gearboxes are sealed against water and dirt. Based on proven automotive gearbox technology, Pinion gearboxes rely on highly efficient spur gearing with two sets of gears connected in series. Depending on the configuration, the gearbox offers 9 or 12 speed in the MGU with an unmatched range of up to 600%.

Using a modular approach towards designing the Pinion E-Drive System allowed Pinion to develop several distinct configurations and versions of the MGU. Depending on the individual use-case, each version has either 9 or 12 gears and is actuated by electric shifting. Furthermore, the software of the system comes in two distinct base tunes – ‘Comfort’ for efficient and harmonic commuting as well as reliable long-distance touring and ‘Performance’ for super-agile off-road riding. An additional dedicated version for Speed-Pedelecs rounds out the offer. Each version comes with a different motor and gearbox configuration featuring individual tunes and settings perfectly tailored to the intended use. MGUs are available in the Pinion E-Line, as E1.12 and E1.9 versions and as E-Speed versions E1.12S and E1.9S.

SEMI-AUTOMATIC ELECTRIC SHIFTING WITH PINION SMART.SHIFT FUNCTIONALITY

Next to offering near-instant engagement at the pedals and an natural ride-feel thanks to the motor and gearbox working in harmony, the Pinion E-Drive System also includes semi-automatic shifting capability. Pre.Select allows the system to automatically shift into the perfect gear for the bike’s speed when coasting downhill, providing the rider with the right gear to get back onto the pedals without having to frantically shift up or down first. And then there is Start.Select. When, for example, a cyclist stops at a traffic light, the MGU can automatically shift into a preselected starting gear. The days of awkwardly trying to get the bike going in the wrong gear are officially over. The MGU and its Smart.Shift System can shift while riding, while being stationary and under load. It can shift for its rider, it can shift manually, it can instantly shift multiple gears at once and its virtually maintenance free.

HMI AND SYSTEMINTEGRATION

Thanks to FIT as a system integration partner, the Pinion E-Drive System offers bicycle manufacturers a high degree of modularity as well as a proven and reliable service infrastructure. The FIT ecosystem offers various interfaces, displays and batteries that can be combined in a variety of ways to create a customized e-bike tailored to the specific application. With a focus on connectivity and individual ease of use, the FIT E-Bike Control App allows the pre-configured MGU setups of all support modes to be customized according to personal preferences.

MADE IN GERMANY

All Pinion units are developed in Germany and assembled at the company’s headquarters near Stuttgart by experienced employees. After completion, each MGU passes an extensive “end-of-line” test run. Here, the quality, functionality and load resistance of the motor-gearbox units are ensured before delivery. The majority of all components belonging to the MGU; from the electric motor to the gearbox and gearing components are produced by our qualified partners in Germany and other European countries. The Pinion MGU project is funded by the German Federal Ministry of Economics and Climate Protection on the basis of a resolution of the German Bundestag.

    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.

    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.

    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?

    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.

    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?

    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.

    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…

    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?

    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.

    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.

    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?
