Because the motor uses the bicycle’s gears, the same 250 W feels different in a low gear on a climb and in a high gear on the flat. That is the point of a mid-drive.

The shell is the fit. Pendix eDrive 300 needs BSA 68/73 mm. The existing bottom bracket comes out. The motor spindle takes its place, and the lockring sets the chainline.
Read the build notes
A press-fit shell, a different width, or a carbon shell with an insert is not this configuration. The workshop measures the shell before the motor is unboxed.

The chainring ships with Pendix eDrive 300. Its size is the one in the manual. A smaller ring for steeper hills is a different setup, not a silent swap.
Read the build notes
Chain, cassette and derailleur stay with the bike if the chainline lands. Pendix includes the ring and the lockring so the motor and the drivetrain meet at a known offset.

Crank arms bolt to the spindle of Pendix eDrive 300. The sensor is torque, so the motor sees how the cranks are being turned, not only whether they are turning.

Pedals are the rider’s own. The motor does not replace them. Assistance follows the pedal input up to 15.5 mph.

Mid-drives fail quietly when the chainline is wrong: the chain climbs the cassette, the stay rubs, the clutch chatters. Pendix eDrive 300 is checked on the bike, not on a bench photo.

A workshop install is the path on file. The quote covers the motor fit. Bent hangers, worn cassettes and brake work are extra.

The offer
What Pendix eDrive 300 actually is
Pendix eDrive 300 is one configuration from Pendix, made in Germany, filed here as a mid-drive. The family is eDrive, generation Catalogue. German gearless mid-drive on the non-drive crank. 250 W, battery included at about 330 Wh.
In the box, as this record has it: Pendix motor, 330 Wh class pack, Charger. Still required before the bike moves under its own assist: BSA 68 or 73 mm shell, Clearance on the non-drive side. A cheaper advert for the same family name is not this list. If the battery, the charger or the throttle differs, it is a different configuration and it gets a different page.
250 W, 25 km/h. German list figures start near €999. British shops have also listed systems from about £1,700. This record uses the euro kit figure.
The price on the card is the maker’s published figure in EUR, or Maker list when no figure was published. Allowances for a missing pack, a charger and workshop time sit in the complete-cost band. They are not a second product and they are not a promise that a random pack will talk to this controller.
The bicycle
The frame this motor is asking for
Pendix lists Pendix eDrive 300 against Hybrid, Road, Folding bicycles, for Commuting, Leisure, Hills. Wheel sizes on the card: 700c, 26, 27.5. The mechanical interface is BSA 68/73 mm. Brakes are disc.
A mid-drive takes the bottom bracket’s job. The shell width, the thread or the press-fit standard, and the chainstay clearance decide it. The bike’s own gears then multiply whatever the motor puts into the chainring, which is why a modest continuous rating can still climb if the shell is the right one.
Pedals stay. This configuration is a bicycle with assistance, not a motorcycle conversion. Sensor on the card: torque. Cut-off on the card: 15.5 mph. Throttle: not fitted.
The numbers
250 W is not the whole story
Continuous rated power for Pendix eDrive 300 is 250 W. Claimed peak is not stated separately from the continuous rating. Torque is not published as a crank or hub figure. Manufacturer stated. Motor mass is not published. System mass, once the named parts are on the bike, is Pendix motor, 330 Wh class pack, Charger.
Peak is a short claim. Street rules, including the Great Britain check on this site, use continuous rated power and the speed at which assistance stops. A controller that can be unlocked does not change the record of the motor as sold. Pendix eDrive 300 is filed in the 25 km/h class: 250 W pedelec class used across the EU, Great Britain and Australia.
In this class the useful comparison is torque and mass, not a bigger watt sticker. A 250 W torque-sensing mid-drive and a 250 W cadence hub do not feel alike, and neither of them becomes legal somewhere else just because the sticker matches.
Pack and charger
The pack is part of the kit
eDrive pack is 330 Wh at 48 V. Lithium-ion The charger is Included charger.
Nominal watt-hours are voltage times amp-hours when both are known. That is stored energy on the label, not usable energy, and not a mileage promise. Cold, load, hills and how full you dare to run the pack all move the distance. Any range sketch on this page shows the watt-hours per kilometre it assumed.
Charge this pack with the charger named for it. The same plug on a higher-voltage brick is the wrong part. A swollen, hot, hissing or sharp-smelling pack is a stop: do not open it and do not keep charging it.
Mid-drive
How Pendix uses this layout
Mid-drive. Pendix eDrive 300 sits at the bottom bracket and drives a chainring, so the bicycle’s gears become the motor’s gears. Climbing in a low gear is the point. Spinning a tiny ring on the flat, at the motor’s expense, is how chains and cassettes die early.
The shell on this record is BSA 68/73 mm. Press-fit, a worn cartridge, or a carbon shell with a hopeful adapter is a workshop measurement, not a yes from the listing. Chainline is the quiet failure: the chain climbs, the stay rubs, the clutch chatters.
Torque sensing means the motor follows how hard you push, not only that the crank is turning. It feels closer to a stronger pair of legs. It also means the sensor, the spindle and the controller are one system.
The workshop
A workshop path, written as a sequence
Pendix eDrive 300 is a workshop install in this record. Doing it yourself does not rewrite the path into a pass. It means the documented route was not the one you took, and the result stays conditional until someone competent has seen the bike.
Warranty as published: Maker warranty. Term is on the invoice.. Labour in the cost band is separate from the offer. A brake service the bike already needed, a new chain, or a hanger alignment is not folded into Pendix’s price to make the total look neat.
The sensible order is measure, then mount, then connect, then the first assisted roll in the stand. Connectors are keyed for a reason. The torque arm, the axle nuts and the connector boots are one inspection at the end, not three trips.
After it is on
The first month, and the parts that wear
Chains and cassettes wear faster because the motor can hold a high torque in a small gear. Shift before the load spikes. A worn cassette is a workshop line, not a reason to suspect the motor first. Keep the chainring that shipped with the kit until you have a reason, in writing, to change the ratio.
Keep Included charger with eDrive pack. Store the pack cool, part-charged if it will sit, and not in a hallway that is your only exit. Pendix’s display, if one is included, is paired to this controller generation. A screen from the next family is not a spare.
My Garage on this device can hold the configuration, who fitted it, and what was still open. That note is for you and for the next workshop. It is not a certificate. If a later notice lands on this configuration, the record is where it should show.

From the library
- What a conversion kit actually includesA motor wheel and a complete system are not the same product. The page should say which one you are looking at.
- Watts, torque, and the sticker that does not mean rangeContinuous watts, peak watts and newton-metres describe different moments. Mixing them is how a listing looks twice as strong as the motor you will live with.
- Speed classes, from 25 km/h to off-roadThe class is a property of the kit as sold. The road you may use it on is a property of the country, and sometimes of the state or the canton.
- Bottom brackets: 68, 73, and the shells that are not BSAA mid-drive does not sit beside the bracket. It becomes the bracket. Width and thread are the fit.
- Cadence sensing and torque sensingOne motor notices that you are turning the pedals. The other notices how hard. The ride, the wiring and the price all change with that choice.
- Converting a folding bikeSmall wheels, hinges and a short front end. The kit has to fold with the bike, or you will fold it once.
