Schindelhauer Arthur IX Ultimate

Built around the Mahle X20 hub motor working hand in hand with Pinion Smart.Shift electronic shifting, Schindelhauer Arthur IX Ultimate is a drop-bar city e-bike for quick, tidy commuting. The battery hides in the down tube, a single top-tube unit runs the system, and a 9-speed Pinion gearbox drives a Gates carbon belt.

Why riders pick it

• The rear hub motor weighs only 1.39 kg yet gives up to 55 Nm, so the bike still rides like a light road machine.
• Pinion Smart.Shift changes gear in 0.2 seconds; Start.Select drops you into your chosen starting gear at a stop, and Pre.Select picks gears by your target cadence.
• TRP HYWIRE brake levers carry the electronic shift buttons, so manual single or multi-gear jumps happen without moving your hands.
• The LightSKIN H1 dropbar front light is three times as bright as the earlier version, and five LEDs sit in the seatpost for rear visibility.
• A 250 Wh battery gives 50 to 80 km depending on level, charges in around 3 hours and comes out for servicing.
