We tested the famous Sourieaux plugs from the formual one, but for our series production they did not do the right job, putting them together took us ages, and we did not want any soldered parts on the bike. So we ended up constructing our own plug for the series production. Its not easy finding waterproof equipment in the market that looks good, is small as well. Thats our result.

Just to give you an idea how complex this product is. It all looks simple in the end when you use it, but getting there and getting it right, functional and reliable is a different story. But this is German engineering at its best. The engine can be taken out in second without special tools, so changing a tire will not be more difficult in the future than with a standard mountain bike.

We have contructed Grace so you can interchange the rear swinging fork completely. So in the future whatever engine we offer you can upgrade the complete back of your bike. It also just looks supercool in the series production.
