Gebla 29er. It’s not strictly built as a separable bike however the rear frame can be detached like any other soft tail bikes so it can fall into the types of bikes I cover in this Tumblr site. Since 29er wheels with tyres mounted on are too fat to fit inside airline legal suitcase or cardboard box or whatever packaging material used the tyres must be totally deflated or even removed from the rims for air travel. This particular bike may also require removal of the front fork as it seems quite bulky to form the part of the separated front half of the bike….
Very curious bike!
