Moustache Samedi 27 OFF 4 Open

About this ebike...

The Samedi 27 OFF 4’s ultra-low center of gravity combined with a powerful Bosch Performance Line CX motor and Plus tyres guarantee a lot of fun with every off-road ride. The Bosch Performance Line CX is the most powerful and the highest torque (85Nm) motor in the Bosch range. It’s the market leader in terms of support. It includes the “eMTB” mode for enhanced performance in MTB usage.

Powered by the 625Wh integrated PowerTube battery for maximum range; assisted by the Deore 11S wide range transmission; the strong Shimano MT400 hydraulic disc brakes and a playful RockShox fork, it invites you to discover more, to lengthen your rides and to push your limits. Its up to you to imagine everything you can do together!

The bike also features the KS-900I dropper seatpost, smooth and efficient, to easily drop your saddle on the most technical trails!
