Did tiptop like to arrive very quickly again

Fast and extremely well packaged delivery! The model ran straight away. The axis is stored in 2 ball bearings. However, the wheel was not firmly attached to it but was only a bore in the wheel. I still had to make up for this. This procedure should be done cleverly so that the bike runs really smoothly. Unfortunately, I didn’t succeed perfectly. Unfortunately, the idea came to me later.

Easy to use. Good for demo
