Comment on Geeko conversion kit from 100g - DON't BUY IT!
When the motor is installed, the bike becomes much heavier and much harder to pedal, when not using the battery. Pedaling becomes six times heavier and the quality of the bike drops to a very heavy and poor bike. This solution is good for people who want to pedal only with the battery and for a distance between 5 and 10 km.
As soon as you put the battery on, the battery level drops by about 20%.
And when the battery reaches about 20%, the battery drains very quickly. According to my test, this battery has a capacity between 5 and 10 km, not 135 km as the seller has advertised.
- If there is a problem, the buyer has no way to return the product. Even if you do not open the box and want to return the product, the seller charges about 40% of the amount the buyer has paid.
I do not recommend these solutions. It would be better to buy solutions where the motor is removable. They are almost half the price.
I don't recommend this seller either.
