Topstone Neo Carbon 4

The Topstone Neo Carbon 4 is for the gravel rider who wants full-power confidence on steep, rough backroads rather than a whisper-quiet lightweight. It's the bike for someone who values climbing grunt and range over the featherweight feel. At $5,500, riders chasing the 'invisible' assist of an SL system, or the lightest possible bike, should look elsewhere — this one embraces its motor rather than hiding it.

The 8.8 reflects a strong motor-and-range showing: the 85 Nm Bosch CX is a proper full-power climber and the 500Wh pack supports up to 75 miles, both criteria this bike scores well on. The BallisTec carbon frame with Kingpin rear flex adds real compliance without a shock, helping ride quality. The honest weakness the whatWedChange flags is character and weight — at 50 lb it's heavier than SL gravel rivals, and the full-power assist trades their discreet ride feel for grunt.

The compromise you accept is weight and subtlety for capability: a heavier bike that climbs and ranges like nothing lightweight can, but never disappears underneath you the way an SL does. If your gravel is steep and long, that's the right call. If you want the drop-bar bike to feel like a normal one, the Specialized Creo 2 is ten-plus pounds lighter with a hide-until-you-need-it motor — at a smaller battery and a higher price.
