I'm looking to sell my car and buy a bike for my commute to work. I'm a very active person so I would like a single speed so I can really get a good workout in. I'm not too keen on buying a bike brand new off the rack. I used to mountain bike and had a fully built Cannondale Cad3 as a teen (a bike I built 100% by myself, frame up).

I recently came across this Kona, but I have no idea how much to offer. I've copied the ad, but it's in French so please bare with me:

Pneu Vittoria Zaffino rouge (neuf)
Guidon Easton MonkeyBar EA70 (neuf)
Frein Shimano 105 (neuf)
Tige de selle Easton EA50 (neuf)
Collet de selle EVO (neuf)
Gusset Single Speed (neuf)
DMR Tension Seeker 2 (neuf)
Potence Easton EA50 (neuf)
Grips rouge (neuf)
Rims Mavic Aksium Race
Headset FSA
Fourche Kona Carbone
Cadre Kona Zing Alu
Chaine Shimano
Gaine de cāble de frein




Any input would be appreciated, thanks!
