Mini Crosser X1 vs X1 HD Max Speed

[petteri]

Hey there.

Mini Crosser X1, according to the specs, has a max speed of 15km/h. Mini Crosser X1 HD, the heavy duty version, has a max speed of 10km/h.

When the HD version's max speed is set to 100% via the Mobility Programmer, it truly is 10km/h.

What have they done differently here, how can the HD version be physically limited to 10km/h, even when set to 100% speed in the Mobility Programmer?

Is there anything to be done to increase its speed to 15km/h, like the normal non-HD version?

I suppose there's some hardware difference and it's not going to be feasible or realistic or cheap to increase the speed to 15km/h of the HD version.

Thanks for any thoughts!

(PS. I'm not a heavy duty user but I still have this version, unfortunately.)

Gearing.
Shorter or slower speed gearing means less current/amps at all conditions, and speeds. And so more range too. And much more torque for carrying more weight or climbing etc.
