In the world of high-performance electric bikes, the Delfast TOP 3.0 has long been a standout. But with the release of the Stealth B-52, it now faces its most serious competition yet. Both models are designed for speed, power, and range, but how do they really stack up? Let’s dive into this detailed comparison.

Speed

For riders who love pushing limits, speed is everything. While many countries regulate e-bike speeds on public roads, private tracks and off-road areas offer the perfect environment for high-speed adventures.

Both the TOP 3.0 and the B-52 can reach a top speed of 50 mph. That’s an impressive feat, especially for an e-bike. However, the question remains: how long can each maintain that speed before the battery starts to drain?

Range

The range of an e-bike depends on various factors, including terrain, pedal assist level, and riding style. Manufacturers typically test on flat ground using throttle-only mode.

The TOP 3.0 shines here, offering an incredible 200 miles on a single charge — a Guinness World Record. The B-52, while still impressive, offers around 60 miles, which is solid compared to most competitors in the market.

Motor Power

Power is key when it comes to performance. The TOP 3.0 features a 3,000 W motor with a peak output of 6,000 W, making it one of the most powerful e-bikes available.

The B-52, on the other hand, uses a 2,000 W motor that can deliver up to 6,200 W of peak power. This means both bikes are strong, but the TOP 3.0 is more consistent, while the B-52 excels in short bursts like climbing steep hills.

Battery Capacity

Battery size directly affects range and performance. The TOP 3.0 is powered by a 72 V 48 Ah battery, which equates to 3,456 Wh — one of the largest capacities in the industry.

The B-52 uses a 72 V battery with 2,000 Wh, which is good but significantly smaller than the TOP 3.0’s. Charging time also differs — the TOP 3.0 takes just 3 hours, while the B-52 needs 4 hours.

Weight

Weight plays a role in portability and stability. The TOP 3.0 weighs 154 lbs, which is heavy but expected given its large battery and powerful motor.

The B-52 is slightly lighter at 112 lbs, making it easier to handle in tight spaces or when carrying it up stairs. Still, it’s far from lightweight.

Price

When it comes to price, the TOP 3.0 is more affordable at $6,599, while the B-52 costs $9,880 — nearly $3,300 more.

Despite the higher cost, the B-52 offers similar peak power and performance. But if you're looking for the longest range and best value, the TOP 3.0 is hard to beat.
