While the Rotom Bike you get on Route 5 in Pokémon Sword and Shield is much faster than walking, it can be improved.

Not only can you use your Rotom Bike to ride on water, it will allow you to speed boost all over the Wild Area and towns. However, the speed boost you activate by pressing the R button only lasts a few seconds and must recharge between uses. Instead of sitting back and waiting a few seconds for another boost, you can pay for upgrades that will lower the recharge time. This guide will show you how to do it.

How to upgrade your Rotom Bike

Throughout the game, you’ll meet several Watt Traders in the Wild Area. While you might rely on them to buy special Poké Balls, they can also increase your bike’s speed if you have the Watts to spend.

You can find Watt Traders at all the marked locations below.

Once you speak to Watt Trader, select the option, “Improve my bike,” which will allow them to increase how often you can speed boost.

You can upgrade your bike three times. The first upgrade will cost 1,000 Watts, the second will run you 3,000 Watts, and the final upgrade will be a whopping 5,000 Watts.
