BH announced the Core, a range of new e-bikes for road, gravel, or commuting. Using a special crankset with 163mm Q-factor, BH aims to satisfy those looking for an e-bike without a super wide pedaling stance. The 504 Wh battery is said to provide 115km worth of assist, and can hit an 80% recharge status after being plugged in only 90 minutes.

2020 BH Core e-bike range

BH isn’t new to e-bikes, but the new Core range represents a big expansion. The line starts with road and gravel frames, but also includes a flat bar road bike, and three commuter-focused ‘Cross’ models with fenders and racks.

BH touts “up to 115km of freedom”, coming by way of an internal 540Wh battery. It charges up quickly, hitting 80% in about 90 minutes.

The motor delivers a claimed 250 watts and 60NM of torque, using four output modes.

While a lot of e-bikes have have a very wide Q-factor, BH kept it as low as possible, at 163mm. This is still wider than most stock road cranks, which are often in the range of 145-150mm.

The Core line touts full internal cable routing, using FSA’s ACR bar and stem system.

A unique display in the stem top cap uses colored LED lights to indicate mode. The LEDs also show remaining battery charge. This can be used in conjunction with their new Core App (IOS and Android) that uses Bluetooth connection to tune the assist modes to your liking.


Sizing options and specs vary by intended use – between road, gravel, and commuting.

Core Race 1.6 and 1.4 road geometry.
Core GravelX 2.6 & 2.4, and Jet fitness geometry.
Core Jet step-through commuter frame geometry.

Very nice looking integrated set up.
Slight potential correction on a slide on Q factor of 163mm.
If crank arms have no curvature from bb attachment area to pedal interface then indeed the 163mm is correct. However, most arms have a slight curvature.
Q factor is measured outside to outside from pedal point.
U factor is the measurement from outside to outside of the crank at bb interface area.
Look at drawings comparing crank sets of BB30 to a BB386 (very close to Shimano).
Wide Q makes you a cowboy – Wide U clinks your shoes.

No worries here because that 3D model isn’t even done properly. The crank won’t even be able to do a full rotation!

Anyways, you’re correct in that it is labelled improperly or they don’t understand what a q-factor is.
