Electric bikes have evolved rapidly in recent years, and with that evolution come new contenders for the top spot. One such bike is the Stealth B-52, which has emerged as a strong alternative to Delfast’s iconic TOP 3.0. In this article, we’ll take an in-depth look at how these two high-performance e-bikes stack up against each other in key categories like speed, range, motor power, battery life, weight, and price.

Speed: The Race for the Top

For riders who love pushing their limits, speed is a major factor. Both the TOP 3.0 and the Stealth B-52 are rated for a top speed of 50 mph. That’s impressive, especially considering most e-bikes max out around 28–30 mph. But while both can reach that speed, the question remains—how long can they maintain it?

Range: How Far Can You Go?

Range is one of the most important factors when choosing an e-bike. The TOP 3.0 is a game-changer here, offering an incredible 200 miles on a single charge. This is not only rare but also holds the Guinness World Record for the longest distance traveled by an e-bike. In contrast, the Stealth B-52 offers a more modest 60 miles, which is still excellent compared to most competitors.

Motor Power: Who Has the Edge?

The motor determines how much power the e-bike can deliver. The TOP 3.0 features a 3,000 W motor with a peak output of 6,000 W, making it a powerhouse for long rides and tough terrain. On the other hand, the Stealth B-52 uses a 2,000 W motor that can spike to 6,200 W. While the TOP 3.0 is stronger on average, both models offer solid performance when you need a boost, like climbing steep hills.

Battery Capacity: Powering the Ride

A larger battery means longer rides. The TOP 3.0 comes with a 72 V 48 Ah battery, equivalent to 3,456 Wh. That’s a massive amount of energy, allowing for its record-breaking range. It also charges in just 3 hours. The Stealth B-52 has a 72 V battery with 2,000 Wh, which is still impressive but significantly smaller than the TOP 3.0’s. Charging takes about 4 hours.

Weight: Heavier or Lighter?

Weight plays a role if you need to carry your bike up stairs or transport it. The TOP 3.0 weighs 154 lbs, making it one of the heaviest e-bikes on the market. The Stealth B-52 is lighter at 112 lbs, though still heavier than most standard e-bikes. While the TOP 3.0 is more stable on rough roads, the B-52 is easier to handle in tight spaces.

Price: What You Pay for Performance

High performance often comes with a high price tag. The TOP 3.0 is priced at $6,599, which is reasonable given its specs. The Stealth B-52, however, costs $9,880—nearly $3,300 more. While the B-52 offers strong performance, the TOP 3.0 provides better value for those seeking maximum range and power without breaking the bank.

Ultimately, both the TOP 3.0 and the Stealth B-52 are top-tier e-bikes, but they cater to different needs. If you want the longest range and best value, the TOP 3.0 is the way to go. If you're looking for a slightly more powerful motor and are willing to pay more, the Stealth B-52 might be the right choice for you.
