This Hypershell cycling mode guide covers test methodology, test results and performance. It brings the relevant details and limitations together so you can compare the options discussed in the article.
The Hypershell X Ultra S is a wearable AI powered exoskeleton. It has a 5,000 mAh battery, motors and arms that strap to the user‘s thighs. The device has a cycling capability designed to assist with pedaling. A 50 year old, 270 pound cyclist tested the Hypershell on a 6.5 mile hilly route against no assistance and against an Engwe LE20 e bike (120 pounds, torque sensor). The results showed that Hypershell did not significantly improve speed or heart rate compared to no assistance. The e bike provided the easiest ride (11.5 mph average speed, 100 bpm average heart rate). The reviewer concluded that for non athletes, an e bike is the path of least resistance. However, for former cyclists with a good bike who want to get back into riding, the Hypershell may be a good option. This review covers the test methodology, data results, cycling mode effectiveness and comparisons with e bikes.

Test Methodology
The reviewer conducted three rides on the same 6.5 mile hilly route in a Chicago suburb.
| Ride | Equipment | Assistance | Notes |
|---|---|---|---|
| Ride 1 | Regular Trek bike (25-30 lbs) | No assistance | Had to stop and rest for a few minutes near the end |
| Ride 2 | Regular Trek bike + Hypershell X Ultra S | Hyper mode at 50% power | Felt device pushing legs down; back sore after ride |
| Ride 3 | Engwe LE20 e bike | Torque sensor motor | Bike weighs 120 lbs |
The reviewer used a Pixel Watch 4 to track heart rate and the Asics Runkeeper app as a backup.
Test Results
| Metric | No Assistance | Hypershell X Ultra S | E Bike (Engwe LE20) |
|---|---|---|---|
| Average Speed (mph) | 9.5 | 9.6 | 11.5 |
| Active Time | 43:33 | 42:04 | 34:21 |
| Average Heart Rate (bpm) | 131 | 132 | 100 |
| Peak Heart Rate (bpm) | 145 | 144 | 116 |
| Light HR Zone (min) | 1:27 | 0:06 | 31:05 |
| Moderate HR Zone (min) | 11:43 | 7:52 | 3:37 |
| Vigorous HR Zone (min) | 30:21 | 33:40 | 0:00 |
Key findings
- Hypershell improved average speed by only 0.1 mph (9.5 to 9.6 mph).
- Hypershell reduced active time by only 1 minute 29 seconds (43:33 to 42:04).
- Average heart rate was almost identical (131 vs 132 bpm).
- Hypershell increased time in vigorous zone (30:21 to 33:40).
- E bike improved speed by 2 mph over Hypershell (9.6 to 11.5 mph).
- E bike reduced average heart rate by 32 bpm (132 to 100 bpm).
- E bike reduced active time by 8 minutes (42:04 to 34:21).
Hypershell Cycling Mode Performance
The Hypershell X Ultra S has a specific cycling capability. The motor attaches to arms strapped to the user‘s thighs, pushing the legs down during pedaling.
What worked
- Felt the exoskeleton actively pushing legs down at 50% power (Hyper mode).
- Did not have to take a break on the second ride (unlike the first ride).
- Felt better after the second ride than after the first.
What didn‘t work
- No significant improvement in speed or heart rate.
- Diminishing returns above 50% power (unit rocked back and forth, causing discomfort).
- Back felt sore after the second ride (may be due to exoskeleton or lack of cycling for 2 years).
Hypershell Vs E Bike: Which Is Better
| Aspect | Hypershell X Ultra S | E Bike (Engwe LE20) |
|---|---|---|
| Price | 1,999 USD | 1,000-3,000 USD (midrange) |
| Weight Added | ~5-10 lbs | 120 lbs |
| Installation | Strap on to body | N/A (whole bike) |
| Speed Improvement | +0.1 mph | +2 mph over Hypershell |
| Heart Rate Reduction | None (131 to 132 bpm) | 32 bpm reduction (132 to 100) |
| Best For | Former cyclists getting back into riding | Non athletes, casual riders |
| Requires Existing Bike | Yes | No (replaces bike) |
The e bike provided a much easier ride. The Hypershell did not meaningfully improve performance for an out of shape rider.
Pros And Cons Of Hypershell X Ultra S For Cycling
Pros
- Allows you to keep your existing bike (no need to buy an e bike).
- Cheaper than premium e bikes (1,999 USD vs 3,000-5,000 USD).
- Straps onto thighs and back (no permanent modification).
- Hyper mode with adjustable power (50% worked best).
- Felt active leg pushing (subjective improvement).
- No break needed on second ride (unlike no assistance).
- Good for former cyclists who want to get back into riding.
Cons
- No significant improvement in speed or heart rate (9.5 to 9.6 mph, 131 to 132 bpm).
- Diminishing returns above 50% power (unit rocks, causes discomfort).
- Back soreness after riding.
- Not a replacement for e bike assistance (e bike reduced heart rate by 32 bpm).
- Expensive at 1,999 USD (many e bikes cost less).
- Requires training to see benefits (device augments skills, does not bestow them).
- Not for non athletes (e bike is path of least resistance).
Frequently Asked Questions (FAQs)
Can the Hypershell exoskeleton replace an e bike?
For non athletes, no. The e bike provided significantly better assistance (2 mph faster, 32 bpm lower heart rate). For former cyclists with a good bike who want to get back into riding, the Hypershell may be a good option.
How much does the Hypershell X Ultra S cost?
1,999 USD. This is below most midrange e bikes (which start around 2,000-3,000 USD) and well below premium e bikes (5,000-10,000 USD).
How does the Hypershell work for cycling?
The device straps to your thighs and back. A motor pushes your legs down during pedaling. You can adjust the assistance level (Hyper mode). The reviewer found 50% power optimal; higher power caused the unit to rock and cause discomfort.
