Battery and electrical safety. Lithium-ion batteries can catch fire if they're damaged or charged wrong. Never open a battery pack, and stop using any battery that's swollen, hot, wet or smells burnt. Every edit to this page is checked by a second person before it goes live.

Brose makes mid-drive units, and Specialized's 1.x and 2.x Turbo motors carry Brose drive names and article numbers. This page explains how to tell which drive you have, how the Brose Drive C, T and S compare, how they match up with Specialized's motor names, and what that means for service.

How to tell which one you have

  • Brose drives. Brose says to identify the drive by the article number on the drive unit. If you can't read it, the number is also in the Settings menu of the Brose Display Allround or Display Central (Brose Mag manual).
  • Specialized motors. Specialized lists a label code for each motor version. It also says 2.x motors have a coated magnesium housing and 12 V light ports, while 1.x motors have an alloy housing and 6 V light ports (Specialized motors).

Brose drives

Brose's manual for its magnesium housing drives lists these figures (Brose Mag manual):

  • Drive C Mag: 50 Nm, article numbers E 57028 (horizontal) and E 41219 (vertical).
  • Drive T Mag: 70 Nm, E 57026 (horizontal) and E 41222 (vertical).
  • Drive S Mag: 90 Nm, E 06855 (horizontal) and E 01680 (vertical).

All three are 36 V with 250 W rated power and IP 56 sealing, with assist to 25 km/h in the manual. Brose's US data sheet for the Drive S Mag vertical lists assist to 20 mph and notes that top assist speed depends on local law (Brose Drive S Mag vertical).

Specialized motors built on Brose

Specialized's motor page lists these versions with their label codes (Specialized motors):

  • 2.1 and 2.2: labeled E01680-100 or E06855-100, 90 Nm, 560 W. Used on 2019 to 2021 and 2022 to 2023 Turbo Levo, Turbo Kenevo Gen 2, Turbo Vado and Como 5.0 Gen 2, and some Turbo Tero models.
  • 2.0: labeled E57026-100, 70 Nm, 470 W. Turbo Vado and Como 4.0 Gen 2 and some Tero models.
  • 2.0E: labeled E57028-100, 50 Nm, 430 W. Turbo Vado and Como 3.0 Gen 2 and some Tero models.
  • 1.3: labeled C97272-100 (Drive S), 90 Nm, 550 W. Gen 1 Turbo Levo and Kenevo, Gen 1 Turbo Vado and Turbo Como.
  • 1.2 and 1.2s: labeled C91143 (Drive T) and C97292 (Drive TF), 85 Nm, 520 W. Gen 1 Turbo Vado, Como and Levo HT.
  • 1.2E: labeled E22243-100 (Drive CB), 50 Nm, 415 W.

The 2.x label codes are the same article numbers Brose lists for its Drive S Mag, T Mag and C Mag in its own manual. Specialized's newer motors, such as the SL range and 3.1, are not on that page. See Specialized Turbo troubleshooting.

What this means for repair

What an owner can do:

  • Keep battery contacts and exposed connectors clean, and check the fixing screws now and then (Brose Mag manual).
  • Clean without creep oils or brake cleaner, never submerge the drive and never use a pressure washer.
  • For a speed sensor fault, check the sensor and the spoke magnet position. For a light fault, check the cables and plugs, then restart. See align speed sensor magnet.
  • On a Specialized, use the app's Bike Status and restart first, as on Specialized Turbo troubleshooting.

What needs a dealer:

  • Yearly checks and big service. Brose says to have the system checked at least once a year, and to have the drive unit inspected by a Brose authorised service centre after 15,000 km (Brose Mag manual).
  • Internal errors that stay after a restart.
  • Repairs, which Brose says need qualified staff and original spare parts. On a Specialized, go to an Authorized Specialized Retailer.
  • Warranty. Specialized covers its motors for 2 years from purchase, or 4 years for the 2019 to 2020 Levo FSR and 2020 Kenevo (Specialized motors).

Brose says never to open the drive unit, and that opening it voids the warranty (Brose Mag manual). Battery, motor and wiring work belongs with a dealer. See when to call a pro and e-bike battery care.
