Pinion provides automated shifting to their mixed mid-drive motor and gearbox.
Pinion has introduced a brand new wrinkle on their built-in MGU—Motor Gearbox Unit. They’ve now added Sensible Shift, a expertise that permits for automated shifting. Pinion grabbed the e-bike world’s consideration once they launched their Pinion MGU in the summertime of 2023. The MGU is a model of Pinion’s gearbox that additionally incorporates a motor, merging a mid-drive motor with a transmission.
As a result of the shifting is achieved electronically—no cables and shifters right here—Pinion experiences instantaneous gear modifications that aren’t affected by whether or not the rider is pedaling or not. Even when the rider is pedaling at full pressure, shifts are fast.
E-bikes outfitted with the Pinion MGU and Sensible Shift will start delivery within the third quarter of 2024. Present homeowners of e-bikes with the Pinion MGU will be capable of go to their supplier for a software program replace so as to add the performance to their e-bike.
The Pinion Motor Gearbox Unit is a exceptional invention. Pinion managed to suit each a gearbox and a motor within the quantity of house that the majority firms fill with a motor alone. Discovering a option to match a gearbox into the house looks as if discovering an SUV with the cupboard space of an 18 wheeler.
The Pinion E1.9 MGU provides riders a 568 % gear vary, which is a wider unfold than any of the 12-speed drivetrains provide. The E1.12 MGU spreads 12 gears over a 600 % vary, a merely unheard-of vary. Motors produce 250W nominally and peak at both 600 or 800W, relying on the configuration, whereas producing a most torque of 85Nm.
Whereas the Pinion MGU outweighs aggressive mid-drive motors such because the Bosch Efficiency Line CX, it eliminates the necessity for a standard drivetrain. So whereas the Pinion MGU outweighs the Efficiency Line CX by greater than 2 lbs. (the MGU weighs 8.8 or 9 lbs. relying on whether or not it’s the 9-speed or 12-speed model, whereas the Efficiency Line CX weighs 6.4 lbs.), it does away with the rear derailleur, cassette and shifter, plus a Gates carbon belt weighs lower than a metallic chain. Finally, an e-bike outfitted with the Pinion MGU can save a pound or extra total when in comparison with a mid-drive motor plus multi-cog drivetrain.
Combining the graceful energy utility of a mid-drive motor with lightning-fast automated shifting whereas concurrently eliminating most of an e-bike’s upkeep wants is next-level fantasy stuff, besides that it’s right here, and actual, and obtainable at this time.
Many of the producers providing the Pinion MGU on their e-bikes are European strains with little to no distribution within the U.S., however there are some manufacturers that may import or produce e-bikes spec’d with the Pinion MGU. They embody Stromer, Bulls, Co-Movement and Precedence.
