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.
If you already know the beauty of riding a tandem, can you imagine the extra enhanced power and range achieved with a durable BOSCH motor and dual BOSCH batteries attached to a high quality tandem bike ready for on or off road touring? The MOUSTACHE SAMEDI handles all of the above with an engineering and design marvel that is designed to go the distance using the combined motors of 2 humans with the mid drive BOSCH motor and the dual batteries with an estimated range of nearly 200 miles! Travel up hills with a top speed of 20 mph, taking the edge off of those long hard climbs. Take your tandem exactly where you want to go.
