This happens even though the engine would have enough power to cope with slopes over ten percent. The reason is the rotation number of The Motor in an electric Trekking bike requires a certain number of Turns to be able to work with full performance. This number is not reached, switches off the engine first-and then quite.
In an E-Bike with mid-engine, the most frequently represented type, it means that the pedals need to be kicked in a certain frequency, so that the Motor helps also. This often means that the wheel must also be in the lowest gear 12 km/h and faster, so that the engine purrs smoothly. On the straight sections and slight inclines, this is not a Problem, in the case of steeper hills and driveways - rich muscle and engine power, however, to reach 12 km/h or to keep. Thus, the Motor in the low speed range, full Power, it must be actually a E-bike.Legal Tuning for E-Bike: creating steeper mountains
Nevertheless, there is a possibility of an E-Bike with mid-engine so that it also creates steeper mountains. The Trick is neither illegal, nor is it Tuning in the original sense of the word. However, the Trick is optimizing the way the engine delivers its performance. Thousands of violations every day: Red light? No matter!

The mid-engine, the driver can change the gear ratios between the drive and the tire. To put it on the front of the Motor, a small pinion is used on the back as large as possible. This also works with a hub gear, a derailleur, however, is stern.de reported. In the case of an E-Bike with hub motor, the Motor is not directly coupled to the Rotation of the wheel here, this Trick works so unfortunately. Heart rate over 200!

In the case of many motors from Bosch is the smallest sprocket will have 14 teeth. If a pinion with 20 teeth will be replaced by one with 14 teeth, you win 30 per cent. If the original sprocket had 18 teeth, you win at least 22 percent. For the exchange of the sprocket of numerous instructions to be found online. Who wants to carry out the work yourself, you will need a gun box and a Set of Allen keys, but also special tool is needed: a tool for bicycles and other tools for the engine. So the crank is disassembled on the side of the pinion with a crank puller. For the pinion you will need a Spider or "Lockring Tool", must match the respective engine.Legal Tuning for E-Bike: More support for the motor at lower speeds
In modern trekking bikes are usually built-in 10-speed cassettes. The largest sprocket has 32 or 34 teeth and should be exchanged against a cassette with a 40 or 42 teeth. The change to the Translation by a further 20 percent. For this conversion you will need a chain whip and a lock ring tool. The cassettes can be very tight, both tools should, therefore, be of high quality. Those who opt for 42 teeth, then the Problem is that the old chain is too short and also needs to be replaced.
the result of the tags should be impressive: If the engine has failed to support earlier at 12 km/h and less, after the conversion, only a speed of 8.7 km/h or when replacing both the pinion – even just 6.4 km/h.
The Motor is not damaged by the tags, after all, only the external Translation is changed, the Motor turns but just as quickly as before. In individual cases, the engine does not accept the Translation, and returns an error message. Then, the Software must be adapted by the specialist workshop. The changes are still completely legal, and the previous maximum speed of 25 km/h is not exceeded thereby.
