Update your Robak 2 with this 19:1 gear reduction mod, which increases torque at the expense of top speed. Benefits include:
- Higher acceleration
- Improved climbing capacity
- Reduced motor startup hesitation with sensorless setups
- More energy efficient at low speeds.
You'll need to print the updated version of the TopDeck rear
and remove the thin piece of plastic from the Chassis using pliers.
