Product Description

The Synapse Neo SE is a gravel e-road bike, with the power, range and comfort to open the roads for everyone.

As well as rough gravel tracks you will be able to tackle the legendary passes of the Tour. Roll through the valleys of wine country. Crank out fast blasts after work or spend the whole weekend riding somewhere you've never been. On the all-new Synapse NEO, the road is now open to all. With its smooth, silent power, comfortably sportive position, and massive range, this electric-assist road bike is built to turn "I wish I could" into "I just did".

The Range to Roam
Bosch’s Generation 3 Active Line Plus drive unit delivers big power and does it so smoothly that you barely notice it - except for how it makes you feel limitless. It's a mid-motor design that’s ideal for road bikes thanks to its light weight, smooth and silent power delivery, and drag-free pedaling beyond the cut-out threshold.

Unlike many e-road bikes, the Synapse NEO is designed with a full 500Wh PowerTube battery, which integrates cleanly into the downtube and packs enough energy for even the longest days. Go as long as you want -the Synapse NEO will get you home.

Connected & Protected
SAVE micro-suspension technology in the frame and fork insulates you from bumps while maintaining your connection to the road. Improved handling, more control, and enough comfort to ride all day.

True Endurance
Endurance Race Geometry positions you forward enough to go hard but upright enough to go long, plus a removable seatstay bridge and hidden fender mounts keep you grinding on any road, in any weather.
