Vélo électrique à double moteur Gbike PTP

1250W / 48V 750W Bafang RearHubMotor. Watts set the ceiling; what you feel on a grade is how much pulling power is available low in the range, where a climb from a standstill actually happens.

Climbing is where an e-bike either justifies itself or does not. A drive unit with real torque in reserve turns the hill you avoid into the route you prefer, and it does it without asking you to hammer the pedals or slow to walking pace. That change in what you are willing to ride to is the whole reason people buy these.

Logan Hydraulic Disc Brakes, 26" x 4" tyres. Stopping distance is set by the contact patch as much as by the caliper: hardware can only ask for as much grip as the tyre has to give, which is why both are quoted here rather than just the one that sounds impressive. Rated to 190.5 kg all in, that is the weight the brakes and the contact patch are being asked to arrest on a wet painted line.

Stopping distance is set by the tyre as much as by the caliper. The best brakes in the world cannot exceed the grip available, which is why contact patch, compound and pressure matter as much on a wet Vancouver morning as the hardware clamping the rotor.

Gears: Shimano 7-Speed Gears. Gearing decides what the motor is asked to do: the right gear on a climb keeps you spinning and keeps the drive unit cool and efficient, and the wrong one grinds through your knees and your range at the same time. Assistance runs to 32 km/h; past that the motor stops helping and the drivetrain is doing all of it, which is exactly when the spread of gears starts to matter.

Gearing decides what the motor is asked to do. The right gear on a climb keeps you spinning and keeps the drive unit in its efficient band, where it runs cooler and draws less; the wrong one grinds through both your knees and your range. A usable spread of gears is worth more than an extra sprocket you never select.
