DescriptionThis the V2 of my wireless système technology for rohloff.I have designed the frame with jean pierre lecacon who has handcrafted it. A plearure To work with my friend and make prototype with à pièce of art home made handcrafter !!!!This little black box is smaller with a home made carbon gear motor box.waterproof ip68.The battery is in the frame and gives 1500 km of range at least.The shifting is upgraded too. You can shift one gear at once even if you stay sticked on the button. But you can use and go to gear 1 to gear 14,as you want , if you press as fast as you can on the gear button. Sorry for the delay.it is hard to work with electronique alone in the dark!!!!
