At Delfast, we are always listening to our customers. Their feedback shapes the direction of our development and helps us create better products. Over 70% of our users are based in the United States, and it was their demand that led us to develop the previous model, the Top 2.0 — a more powerful version of the original Top 1. The Top 2.0 is an electric bike designed for long-distance travel, not limited by traditional roads. However, even this model has its limitations.

While the Top 2.0 is closer to a light enduro bike than a classic mountain bike, it still couldn’t meet the needs of our diverse customer base. Our users live in all kinds of climates and terrains — from snowy mountains to desert dunes. We needed a bike that could handle extreme conditions and stay active throughout the year, not just sit in a garage during winter.

This led us to develop the Delfast Offroad TOP 3.0. The concept was simple: take the power and range of the Top 2.0 platform and enhance it with off-road capabilities. But it wasn’t as easy as just adding a few features. The performance of the Top 2.0 is so high that it exceeds what even the most elite athletes can achieve. This meant the bike had to be built to withstand much higher stress and wear.

Designing an off-road electric bike required careful consideration. We had to think about suspension systems, tire pressure, and how the bike would perform on uneven surfaces. It was like building a lightweight off-road vehicle from scratch. We tested different components to find the right balance between speed, range, and durability.

For example, we initially used a high-quality Rockshox Bulto front fork, but after testing, we found that it didn’t offer much practical benefit over our custom rubber solution. In most situations, the rubber alone provided sufficient shock absorption. That’s why we opted for a reinforced rubber design that can handle much greater loads than standard bicycle tires.

As a result, while the speed and range of the Offroad model are slightly lower than those of the Top 2.0, the versatility and all-weather performance have significantly improved. It handles loose soil, snow, and sand with ease. Plus, like all fat bikes, it offers a higher carrying capacity. We’ve included a comparison chart below to show the differences clearly.
