All Terrain ULTRA e-Bike

---

Some components interchange across the line of SUN TZU ebikes, like saddles, seat posts,

handlebars, and grips. The ebike-specific components, however, like batteries, controllers,

displays, and motor do not interchange.

SUN TZU ebikes can have the speed limit changed using the settings in the control panel and

can be set as low as 14 MPH if desired to comply with local laws. SUN TZU ebikes can also have

the throttle unplugged and removed (but will continue to run on pedal assist) if desired in

locations where throttle bikes are not permitted.

This is a safety feature to prevent you from accidentally engaging the throttle while parking or

standing with the bike, if you forget to turn it off and then hit the throttle accidentally.

You can engage the throttle at any time while you are pedaling. If you are at a dead stop, you

can push the throttle, start pedaling (about one pedal revolution), then stop pedaling, and the

bike will stay in throttle mode

Lithium-Ion ebike batteries use a similar technology to your laptop or mobile phone. They can

absorb about 300 charging cycles before performance starts to degrade. Afterwards, they can

continue to be recharged, however, their capacity will decrease.

Yes, it is possible to put a suspension fork on the SUN TZU line of ebikes. You would need a

replacement fork with these specs: 1 1/8” to 1.5” tapered steerer tube, 51mm IS mount for

disc brakes (or a 74mm mount with an add-on adapter to 51mm), 26” wheel size, and the axle

type dropout style. Selecting and installing a suspension fork is probably a job for a bike shop.

Yes, you can add a suspension seat post to your ebike. Shop for a model with the same

diameter as the seat post you are replacing. The seat post diameter is stamped on the post,

near the minimum inserion mark.

We ship the EB01 ebike in a “Class II” configuration to meet ebike laws which have been

adopted in many states. The user can modify the speed limit using the settings, for example, if

you live in a state without ebike laws, or if you are riding on private property. During our

testing, we have found that the EB01 can achieve about 28mph on flat ground if you remove

the speed limit.
