Bafang® BBS01B-ETM 36V 250W motor kit (DPC-18 display) with Samsung 35E cell 36V 17.5Ah downtube battery
Latest model of BBS01B-ETM 36V 250W motor from Bafang (model reference 'MM G340.250'), suitable for converting over 90% of bicycles already on UK roads into an E-bike. The motor fits directly at the cranks, so the majority of the bicycle remains unchanged.
The ETM, meaning extra torque model, has several uprated internal components. The motor winding is more substantial and the controller has uprated components (capacitors and mosfets) meaning it can power at a higher current thus producing greater torque (peak 100Nm compared to 80Nm for the BBS01B).
These motors have several new features compared to the previous BBS01 motors, such as revised controller design with improved gasket, additional connections for direct gear sensor input and a 6V power output for lighting.
The supplied display is the latest model 'DPC-18' colour display allowing to select from up to 9 gradually increasing levels of assistance depending on the terrain/winds.
The bike rides as normal when power is switched off without the drag, weight or resistance that can be associated with hub motors.
Considered superior to hub drive systems, especially for hill climbing, torque and efficiency, the BBS01B-ETM are arguably the best way to maximise the 250 Watt power limit allowed in the UK to qualify as an EAPC.
Pedal assistance set to cease at 15.6 mph (25kph), the UK maximum assist speed limit for EAPCs.
The battery is the new Reention Polly case, designed to mount on the bike's downtube. The battery uses 50 Samsung INR18659-35E cells.
The battery comes supplied with a 2A charger (UK 3-pin plug).
Both motor and battery are upgraded with Anderson Powerpole connectors, superior to the standard bullet connectors commonly supplied.

Suddenly, journeys that previously felt too far to take the bike, routes that include steep hills previously avoided no matter how great the views or pretty the scenery, become a breeze with the addition of electric pedal assistance.
Unlike most E-bike systems produced up until now that would power from the wheel hub, the Bafang BBS01B-ETM (MM G340.250) powers from the cranks. This provides high torque power directly at the cranks, meaning the rider benefits from motor power through all of the gearing available at the rear wheel.
Also, a mid-drive lowers and centres the bike's centre of gravity making the ride feel more stable and controlled. Mid-drive is fast becoming the favoured choice for a lot of off-road and hilly commuter bikes.
* Available for most standard 68-73mm shell and certain BB30 press fit bottom brackets.
