Question about Kokua Jumper

10-15 minutes if Junior hadn't been jumping around beaming :-)

I managed it, took about 15-20 minutes. I took quite a bit of time to admire everything. The bike is of excellent workmanship! I didn't have the seventeen key, so I used an English one. I turned the wheel upside down, then it stands on the saddle and steering wheel. The wheels are easier to mount.

Ich hatte max. 20 min. Er hatte nur 5 Min: https://www.youtube.com/watch

It took maybe 30-60 minutes. But it went well and easily.
