There are several contenders in the electric bike market vying for the title of the fastest and most efficient e-bike. Among them, the Stealth B-52 stands as a formidable challenger to the reigning champion, the TOP 3.0. Let’s delve into the details to see how these two beasts compare.

Speed

Speed enthusiasts often push their electric bikes to their limits, especially on private property or racetracks where regulations are less restrictive. Both the TOP 3.0 and the B-52 can reach a top speed of 50 mph, which is quite impressive. However, the question remains: how long can they maintain such speeds? In terms of endurance at high speeds, both models deliver solid performance, making them ideal for those who enjoy a thrilling ride.

Range

The range of an electric bike is one of the most crucial factors for potential buyers. It refers to the maximum distance the bike can cover on a single charge. Factors such as terrain type and the level of pedal assistance required play a significant role in determining the range. While there isn’t a standardized method for measuring range, manufacturers typically test under controlled conditions, such as flat terrain using throttle-only mode.

The TOP 3.0 boasts an incredible range of 200 miles on a single charge, setting a benchmark that few e-bikes can match. This achievement even earned Delfast a Guinness World Record for the longest distance traveled by an e-bike on one charge. On the other hand, the B-52 offers a more modest range of 60 miles, which is still commendable compared to most e-bikes on the market.

Motor

The motor type directly impacts the power output of an electric bike. More powerful motors generally tend to be larger and heavier. Therefore, there’s always a balance to strike between power and size/weight.

The TOP 3.0 is equipped with a robust 3,000-watt motor, which can deliver up to 6,000 watts of peak power. The B-52, while not far behind, features a 2,000-watt motor capable of reaching 6,200 watts of peak power. Peak power is particularly important during challenging situations, like climbing steep hills. Although the TOP 3.0 has a slight edge in average power, neither bike will disappoint when a boost is needed.

Battery

Battery capacity is essential for maintaining the energy required by the motor. The TOP 3.0 sports a massive 72-volt, 48-amp-hour battery, equivalent to 3,456 watt-hours. This gargantuan battery capacity contributes significantly to its extended range and is a key reason why the TOP 3.0 can achieve such impressive distances on a single charge. Recharging this behemoth takes about three hours.

Conversely, the B-52 is fitted with a 72-volt battery offering 2,000 watt-hours. While this is a respectable battery capacity compared to most e-bikes, it’s still dwarfed by the TOP 3.0’s battery. The B-52’s battery takes four hours to charge fully.

Weight

The overall weight of an e-bike can be a deciding factor depending on your needs. If portability is a priority—such as carrying the bike up multiple flights of stairs—lightweight options might be preferable. However, heavier e-bikes tend to provide better stability and durability on rough terrains.

High battery capacity, immense power, and extended range come at a cost. The TOP 3.0 tips the scales at 154 pounds, making it significantly heavier than most e-bikes. The B-52, weighing in at 112 pounds, is noticeably lighter but still heavier than many competitors.

Price

When purchasing premium e-bikes, price doesn’t always correlate with quality. The TOP 3.0, with its superior range and slightly greater power, retails for $6,599, which aligns well with its features. Meanwhile, the B-52 carries a hefty price tag of $9,880, creating a substantial price gap between the two.
