Velo Orange’s dynamo hub can be switched off to cut internal drag
Dynamo hubs are fantastically convenient. They power your lights whenever you ride, meaning you never have to change batteries. And because they are sat inside the wheel hub, they’re safe from the bumps and whacks that can damage external bottle-dynamos.
But they are also a drain on your leg power, dragging at your every stroke with their magnetic generators. Velo Orange’s Switchable Dynamo Hub fixes this with a switch that disengages the dynamo, letting you cycle drag-free by day, only engaging the lights at night. This is done by twisting the big disk on the side.
The aluminum hub comes in quick-release or regular fixings (weighing 750g and 685g respectively), is sized for 100mm frame spacing and can be had drilled for 32 or 36 hole rims. The output is six volts, three Watts.
Couple this with an internally geared hub at the rear and you’ll have a bike that packs a lot of function, while maintaining a very clean look. The Velo Orange Switchable hub costs $130, and is available now.
