Keep the Bike. Add the Power.

OTARO Spark EV Conversion Service

The OTARO Spark Conversion Service transforms your existing bicycle into a powerful electric ride without requiring you to purchase a completely new bike. Designed for riders who want more range, easier climbs, and improved everyday versatility, Spark offers a practical way to experience the benefits of electric mobility while keeping the bike you already know and love.

Every rider is different, which is why every conversion starts with your bike. Whether you're upgrading a commuter, mountain bike, cruiser, hybrid, or daily rider, our team works with you to determine the best setup for your goals, riding style, and budget. The result is a personalized electric bike built around the platform you're already comfortable riding.

Our professional conversion process includes component selection, installation, testing, and setup to ensure your bike performs safely and reliably. By combining proven electric drive systems with expert installation, Spark delivers smooth power, improved climbing ability, and a more enjoyable riding experience.

For many riders, converting an existing bicycle is a more affordable and sustainable alternative to purchasing a new e-bike. Instead of replacing a bike that already fits your needs, Spark gives it a new purpose—unlocking electric performance while preserving the ride you've grown to love.
