Our review
Comparative analysis · updated October 2, 2026Discontinued by Hypershell and not sold in its US store. It was the lowest-spec way in: 400 W, 6 modes and one battery. The X Pro S and the X Carbon, with twice the power, are now the Hypershell entry points you can order in the US.

Pros
- A gentle first step: 400 W and 6 modes make for an easy introduction to powered assist
- 5.5 lb with its battery, the same weight as the 1,000 W X Ultra
- Full recharge in 1 h 30 over a plain USB-C connection
Cons
- Discontinued, and not listed in the US store as of Oct 1, 2026
- One battery only: 9.3 miles, so you must pace the assist over a long day

Who it's not for

Frequently asked questions
Can I still buy the Hypershell X Go in the US?
Not from Hypershell: its US store did not list the X Go on Oct 1, 2026, and the maker has discontinued the model.
The X Pro S and the X Carbon, both 800 W, were the lowest-priced Hypershells in that store ($999 each, checked Oct 1, 2026).
Does the assist really help, or is it a gadget?
The assist is clear uphill and with a loaded pack, and almost irrelevant on flat ground.
It is not a performance tool: it is for climbing and carrying, not for records on flat ground. The motor can also warm up during long use.
Alternatives
Dnsys X1
Hypershell's direct rival: 900 W and 40 N·m for $110 less than the X Carbon. In real use, range and strap comfort fall behind.
Hypershell X Carbon
800 W, two batteries, a carbon frame, GORE-TEX fabric and titanium hip levers, all at the price of the one-battery X Pro S.
Hypershell X Pro S
The entry point to Hypershell's S series: 800 W and 10 modes on the newest platform, with one 10.9-mile battery in the box.
