I don't know how true this is, but fun to add.

This is the only picture (top image pink red) I could find of an old liberia but I've seen an older looking version on sale so it's feasible to predate the crazy horse :roll:. Generally the first french Mountain bikes are considered the MBK City/ranger or the peugeot crazy horse 1982.
"1978 : Gérard Biboud returning from the USA, decided to build a moutain bike that he'd witnessed evolving on the other side of the Atlantic. The first presentation in france would be at the Salon de Paris where Ets Libéria would be the first to make and sell Moutain-Bikes in france, VTT (Vélo Tout Terrain) in france.
1980 : A 28yr genevian comes to Grenoble to see Ets Libéria, with an ambitious idea, to ascende to the roof of Africa. Ets Libéria, only makers of mountain bikes in france, would study and produce a special mtb. Eric Doutrelepont would climb mount Kilimandjaro ( Uhuru : 5 895 m). This climb would be done in 3 stages. 2 750 m, the other 3 800 m and the last at 5 000 m. It would take Eric 1 day and half to go back down"
Apparently this bike has internal hub braking, internal rear gearing with freewheel and 3 chain ring derailleur. So you have 3 thumb shifters
