Looks very rare trials bike from a tiny manufacturer (used to big and famous in 70s), very radically designed and fully thought-through trials bike. To my knowledge OSSA's currently the only trials bike on the market that is designed and built from scratch with just trials passion in mind, not just copying others like most trials manufacturers tend to do to keep the traditional layout and beaten track bullcrap going.
Although hard to find they can be picked up dirt cheap currently since OSSA is on the verge of bankruptcy. Like all other all-passion manufacturers in the past they've paid the price with their massive R&D investments for pushing the technology boundaries (first 2T EFI in the sector, it's the smoothest and most predictable pulling trials engine currently on the market, radical reversed-cylinder engine and radical frame design, also the lightest bike in the class), had zero advertisement and just didn't sell enough bikes to justify the high R&D costs, let alone afford some top rider like Toni Bou or Adam Raga for showcase and visibility.
Unlike most trials bikes that mostly each have their own quirks I felt at home immediately I rode OSSA for the first time, everything is just designed and put right with this bike. Since price is also very low I had to get one myself, now after few months owning I love mine to bits! Even if OSSA trademark dissapears again I'll be keeping mine for years, just a fab ultralight trials bike to keep 'em proper riding skills tack sharp!
(on a second though actually might have to get second s/h one into family since wifey keeps nicking it from me, she just loves riding that OSSA, lately too much in fact)
I guess we WMB folk tend to like 'em more radical bikes, anyone else loves riding their OSSA trials bike here?
