Synapse Neo Allroad 1 SRAM Force AXS XPLR 12sp

The range is straightforward, with two builds built around the same carbon frame, Bosch SX-based system, and all-road chassis. The Synapse Neo Allroad 2 is listed at $6,049 and uses a Shimano GRX 800 2x12 drivetrain with 48/32 chainrings and an 11-34 cassette, paired with aluminum 700c wheels and Shimano hydraulic disc brakes. That setup makes it the more road-oriented and lower-cost entry into the platform, and reviewers noted that it delivers the same core frame-and-motor experience as the top model.

The Synapse Neo Allroad 1 steps up to $7,699 and swaps to a SRAM Force AXS XPLR 12-speed build. Reviews singled this version out for its premium shifting performance and more upscale overall presentation. Across commentary, the main value argument is that both bikes share the expensive parts that matter most: the carbon chassis, integrated design, and Bosch light-assist system with 400Wh internal battery. The tradeoff is that neither build is cheap, and some reviewers felt details such as the aluminum wheels and basic 2A charger were less generous than expected at these price points.

Reviewers are broadly aligned in describing the Synapse Neo Allroad as a high-quality endurance-oriented e-bike with a notably natural assist character. Transition Vélo praised its comfort, easy learning curve, strong finish quality, and low weight for a mid-drive e-bike at roughly 14 kg, while Maillot Magazine and Bike Café both highlighted the Bosch Performance Line SX system for delivering assistance that feels progressive rather than abrupt. Several testers also noted how cleanly the bike rides above the assistance limit, with little drag from the motor, which helps it behave more like a conventional endurance bike on faster flat sections and descents.

The recurring strength is its balance on pavement, broken asphalt, and smoother gravel. Reviewers consistently found the upright, compact riding position effective at reducing fatigue over long rides, and they praised the bike’s stability at speed, helped by its long rear end and planted chassis. At the same time, there is a clear limit to its gravel capability. Tour-magazin questioned whether it is really an e-gravel bike at all, noting that traction runs out quickly on loose terrain, while Bike Café reported that the more aggressive assist mode can provoke rear-wheel slip on steep, technical climbs. A few criticisms came up repeatedly: the frame can feel firm rather than especially plush, tire clearance tops out at 45 mm, the integrated setup may complicate maintenance, and the supplied 2A charger feels underwhelming at this price level.
