Stealth B-52 E-Moto Bike
Stealth Bikes is headquartered in Melbourne, Australia. Being surrounded by rugged terrain, they make bikes that can conquer that terrain. It started in 2008 when Stealth’s founder John Karambalis combined his 30 years of engineering, design and off-road experience to create the original Stealth Bomber.
Of course, owing to the monster power and throttle control, the Stealth bikes are not likely to find fast favor in more traditional e-bike circles. Sure, the B-52 has pedals, but this is the very type of e-bike that brings motorcycle analogies to mind with e-bike detractors.
Over the years the Stealth line has expanded, and their top-end offering is currently the B-52 and the H-52, which has a traditional motocross-style seat and footpegs instead of pedals.
The B-52 comes with a chromoly monocoque frame and swingarm, a DNM USD-8 air-spring fork with 200mm of travel, and a DNM rear coil-over air-spring shock with 250mm of travel. Both front and rear have an adjustable rebound, preload and compression settings.
The bike can be custom-configured to a myriad of customer desires, offering everything from custom paint colors to options like DVO Emerald carbon composite forks, all selected at the time of the order on Stealth’s website. Our test bike was pretty stock, but had the kickstand, which costs an additional $180. That’s pretty costly for a kickstand, but remember, this is no ordinary 40-pound e-bike it’s supporting. You can customize the color on the frame/swingarm for $1000, rims for $600 and pedals for $100. If you max out the specs on the bike, it goes from $10,400 to nearly $15,000.
The pedaling setup uses a 9-speed SR Suntour V-Boxx FR9 gearbox, with the cranks attached at the bottom and shifting actuated by a twist-grip on the left side of the handlebars. This particular setup is interesting because SR Suntour doesn’t recommend shifting under load, though that load is at the cranks, not the motor, so you can still be on the throttle while shifting. The Q-factor isn’t awful, but…
