Sushi Bikes is an e-bike store with focus on modern design, affordability, and sustainability, making green urban mobility accessible to all. Operating on Shopify, Sushi Bikes face increasing demand for their e-bikes and equipment. To optimize the shopping experience and keep customers satisfied, several measures like image optimization have been tried out but a more comprehensive page speed solution is required.

"Thanks to Speed Kit, our webshop is now turbocharged, just like our Sushi Bikes! It's like giving our customers the thrill of a high-speed ride while browsing through our products, ensuring a fast, smooth, and unforgettable experience."

Sushi Bikes integrated Speed Kit, a unique browser-based caching solution. Speed Kit works by intelligently caching and delivering optimized web pages, resulting in faster loading times and improved user experience. With Speed Kit’s Shopify app, the integration process is remarkably swift and effortless, completed within just three simple clicks. As a result of Speed Kit’s advanced technology, Sushi Bikes’ shop experienced a significant boost, particularly in Core Web Vitals such as First Contentful Paint (FCP) and Largest Contentful Paint (LCP), showcasing a remarkable increase in speed.


The improvements were measured with an A/B test during the onboarding phase and delivered impressive results. With Speed Kit’s real-user monitoring (RUM) data, various analysis have been made and show significant accelerated loading times.
