Classic 25/45

Our classic

Classic 25/45 – 45km/h e-bike with 500W and 100Nm

Also available in 25km/h with the equally powerful 500W mid-motor.

If you need to pull a trailer or start uphill, the Classic and Comfort models are best. Due to its characteristics, the mid-motor reacts faster and with more torque when starting. For a commute of less than 20km, the Classic and Comfort models are wonderfully sufficient; above that, the Power45 is basically more suitable.

The components

/ The electric motor

500 watts of peak power support you during acceleration or when starting uphill. The engine is equipped with a torque sensor that measures the rider’s force and adjusts the engine power accordingly. This gives the feeling of riding a normal bike with a lot of tailwind. Also, the engine is equipped with an idle, so you can drive without a battery without much resistance from the engine.

The Classic is available in 25km/h, as well as in 45km/h. An upgrade to 45km/h is possible at any time. The components are the same for both designs. The only difference is the gear ratio and the maximum speed at which the motor supports you.

For 45km/h you need a mandatory liability insurance with yellow number and at least a class M driver’s license.

Frequently asked questions

In order to save paper and protect the environment, you can find the latest operating instructions for the Classic 25/45 here.

The Classic has a high entry compared to the Comfort.

Unlike the Power 45, this model is designed for slightly shorter distances.

The advantage over the Power 45 again is on the one hand that it is cheaper and still supports up to 45km/h, on the other hand it is suitable for trailers.

  1. AureusDrive relies on proven and robust technology for its components. To give you the best value for money, the components have also been selected according to this principle.
  2. We distribute our e-bikes ourselves without intermediaries. This allows us to offer our customers a lower price than our competitors.
  3. We deliberately did without additional features such as Bluetooth communication, 24-speed shifting or GPS tracking. Our g45c is simply e-bike.

The recommendation for the Classic frames is as follows:

M: height 175cm – 195cm

S: height 160cm – 175cm

These are guideline sizes which usually fit very well. If the seating position does not fit after a long ride after a purchase, there is the possibility to change the handlebar stem with us or our partners.

Further, we also have adjustable stems in the range, with which you can optimally adjust your seating position:

See here:

If you order this we will mount the stem immediately.

Note that the recommendations are different for each model.

Yes, of course. Under “Service” on our website you can register for this with your nearest partner. Since we use standard parts can also make any bike mechanic a service on our AureusDrive.

When fully discharged, a complete charge takes between 3 and 4 hours. Our charger charges the battery with a rather small current of 3 amps at 48 volts. This is very gentle on the Samsung battery cells and thus a long battery life is achieved.

We have a battery with a capacity of 670 Wh. The range of the battery depends on various influences such as incline, weight of the rider, ambient temperature, support level and cadence as well as tire pressure.

The following ranges should be possible:

On the 45km/h model:

Eco (70 km), Tour (50 km), Speed (40 km), Turbo (35 km)

On the 25km/h model:

Eco (110 km), Tour (80 km), Speed (60km), Turbo (50 km)

We supply the e-bikes in white, black, and green. Other colors and/or own branding are possible. We ask to be contacted in this regard.
