What needs clarification
Manufacturer information does not always agree or explain every option. Here is what remains unclear for this device.
- Battery options and range
The supplied product sheet lists 50 Wh and 99 Wh batteries and different runtimes by edition, but does not confirm which battery goes with each figure. The brochure separately claims up to 25 km per battery under specified laboratory conditions. These figures are not interchangeable. Confirm the battery included in your chosen package and the conditions behind its runtime claim.
Would this fit what I want to do?
Explore the activities below. For hills and stairs, check assistance in each direction.
Keep up
CAPABL suggestionHip assistance for walking, with a resistance mode for exercise. Worth exploring for walking with other people. Assistance does not guarantee a particular pace.
Travel
CAPABL suggestionHip assistance for walking, with a resistance mode for exercise. Worth exploring for walking during a trip. Check fit, packing, charging and airline battery rules separately.
Hiking
Manufacturer-listed useLong days on your feet
CAPABL suggestionHip assistance for walking, with a resistance mode for exercise. Worth exploring for days with repeated walking. This does not confirm comfort or battery life for a whole day, or help while standing still.
Training
For training, the device must add resistance to work against. Check which model and exercises this covers.
Manufacturer-listed useGoing uphill
The brochure describes AI adaptive assistance during uphill climbs.
Going downhill
The brochure describes impedance/resistance mode for descents. This does not establish braking or fall prevention.
Going up stairs
The brochure specifies slow-paced stair climbing; it does not establish handrail independence.
Going down stairs
Not confirmed
