Thumb Throttle: CrossCurrent/CrossCurrent AIR/OceanCurrent

Here is what the thumb throttle looks looks like on the Current-Series e-bikes.

On most e-bikes with throttle and pedal assist, the throttle overrides the pedal assist or the pedal assist overrides the throttle. Either case it super counterintuitive and jerky. The rider loses confidence in the throttle and the magic of the pedal assist vanishes.

We have designed our throttle in a very smart way. Basically the throttle and pedal assist systems are always active. The controller (ECU) is comparing which input signal will have the greater effect in real time. It is doing this comparison super fast, like 1,000 times a second. The end result is that you can transition from throttle to pedal assist seamlessly. It works exactly how you expect it to work.

That's a torque sensor. ;)

@Tora Harris The website says that the throttle will convert the bike to a class 2 e-bike. It looks like the throttle ships along with a display which does not have the sport mode, is that just an optional display?

Yes it is an optional display.
Strange! Given the kind of perfectionist that Tora is, it doesn't seem to make sense why they would ship a whole new display when most customers are probably going to have to just trash it.

Tora has said before that they interpret the CA law to mean that a throttle-equipped e-bike is not allowed to go over 20mph assisted.

CCs are shipped around the world and they have different regulations everywhere. The kit makes the bike adaptable to most any regulation (without digging into software) The CC is designed to comply closely with European S-Pedelec 45Kmh / "350 W" regulations.

Tora, can one use the throttle to ease pushing or walking alongside a bike or is the control not delicate enough to move it that slow? One instance of this might be an ascent too steep to get up with your weight on bike. Pushing a 51 lb without assist could get old fast

It has walk mode, just hold down the "-" button and the motor will go at walking speed.

Tell me if I'm wrong but isn't the hyper bike advertised as having a 30 mph throttle only mode and if so why can't we all have that option?
The HyperFat runs at 35 Amps and the OceanCurrent like 15 Amps. The motors are very different. If you run the OC at 35A, (assuming the pack can do that) it will go 30mph, but then just melt and people will say that we have poor quality bikes.

The HyperFat is made for the non-public roads... like the gas powered dirt bike cousin that can go as fast as you willing to hang on as long as they dont spit out too many toxic gases. The HF can be programed it down from the LCD display to tame it down to fits the legal definition of e-bike at 20mph or 28mph in assist. Anything with throttle speed over 20 mph is considered illegal. The OC with throttle alone unrestricted would go about 24-25 mph, but unless you turn the pedals forward the law restricts to 20 mph or less using throttle only.
