Tandem Samedi 27 x2 eMTB


Tandem Samedi 27 x2 eMTB

BOSCH Performance CX 1000 Wh !


And what if we do an e-tandem ???

And presto, that’s how a new challenge begins!



"Wow, that’s not so stupid! It’s a great idea, to increase and combine effort, or when the two riders do not have the same level of fitness, with children, with a trailer, to go further, to bomb uphill (because everyone knows that a tandem… it bombs along especially on the flat)."

1st challenge: the motor...
Put it at the front, easy… but it’s impossible to synchronize the cranks due 
to the motor freewheel… so, forget that if you want to maintain a decent ride. Therefore we decided to put it at the rear… but we had to innovate! 
So we created a unique interface and special cranks to link the front and rear cranksets despite the motor being at the back.

2nd challenge: the stiffness!
Fortunately we already have our triple cavity tubes that have made our task easier!

3rd challenge: the range.
And for this we can thanks Bosch who have developed a «Y» «DualBattery» wire to safely connect 2 batteries in order to get an incredible capacity 
of 1000 Wh! The system intelligently manages power between the two batteries during charging and discharging, which increases their lifetime.
