Stealth Electric Bikes redefine the ride experience. With a top speed of 30 mph (Fighter) and 50 mph (Bomber) in virtual silence, they are the toughest and most powerful hybrid electric bikes available anywhere in the world. Stealth bikes combine cutting edge technology with pedal power allowing the rider to experience the freedom, silence and agility of a mountain bike, with the acceleration, speed and thrill of a dirt bike.
I wanted to include an electric bike that would be ideal for off-road and trail bike touring, and I think the Bulls E-Stream Evo 3 27.5 Plus is it. This hardtail mountain bike would be perfect for bike tourists going out on the trails for a few days. You could conceivably go for a few days without needing to recharge the Brose 650 watt hour battery, so even if your camping in the wilderness with nowhere to recharge for 60-100 miles you would likely be fine on battery life.
The complete integration of the Optibike is achieved from the ground up with a disign focused on high performance, safety, and ease of operation. Front and rear long travel suspension with disc brakes gives the rider confidence. The fully integrated package gives the utmost in convenience allowing the rider to ride on road, off road and the up or down the steepest hills. Optibike is in a class of its own. The Monocoque frame has sleek styling and a low center of gravity for stable handling. All electronics and long-running battery are safely housed inside the frame.
E-bikes are zero-emissions vehicles, as they emit no combustion by-products. However, the environmental effects of electricity generation and power distribution and of manufacturing and disposing of (limited life) high storage density batteries must be taken into account. Even with these issues considered, e-bikes are claimed to have a significantly lower environmental impact than conventional automobiles, and are generally seen as environmentally desirable in an urban environment.
“Our first-generation bike used the same type of 36-volt, 10-amp-hour battery,” he says. “It got between 20 and 30 miles of range, and that’s riding with pedal assist. Using just the throttle you might get 20, less if you’re running on sand or up hills. The charge time is also problematic; with that kind of battery you’re looking at four to six hours, not 90 minutes.”
Electric bikes are categorized by classes: Class 1 ebikes are pedal-assist cycles with a top speed of 20 mph. (Some localities have banned Class 2 and Class 3 ebikes, which are throttle on demand.) The trick to using a Class 1 bike is to, well, pedal. “If the pedals stop, the bike doesn’t go,” says Saltvold, who describes using an ebike as akin to running on a moving walkway in an airport terminal. Whitaker notes that customers say they switch off the pedal-assist to get more exercise, then turn it back on when going up a hill or wanting to increase their speed.
The wiring could be better, but I think I’m going to make some adjustments to that myself. It’s also worth noting that the motor is in the rear hub just like a basic commuter ebike. This will affect the way it feels, as bottom bracket motors give a more seamless “pedal assist” experience. Of course, this bike seems like it’s made as practical transportation. To me, anything that gets cars off the road is a good thing so lets take it for a ride.
All Kalkhoff bikes come with lots of extras: hub or motor powered front and rear lights, bells, fenders, chain guards and racks. Some include a built-in quick-lock or a rack-mounted pump. There are a number of features available for the discerning cyclist, whether it's the Magura hydraulic brakes, the B&M super-bright hub-powered headlight, the top-of-the-line Shimano internal hub or derailleurs or the three-layer powder-coated paint process.
To be honest, this bike is really designed for city commuters or kids riding around the suburbs. The fact that it’s foldable will let you carry it on the bus, on the train or even on the plane. It’s just not designed for heavy riding, long distances or tough terrains. If you want something sleek and fabulous at a fraction of the cost of most other e-bikes, this baby’s for you.
This article first appeared in Electric Bike Report in June of 2013. Since then, we’ve made some changes to our motor selection - our Direct-Drive motors are now all High-Torque 6x9 wound, so they run slower (approximately 15mph at 36v or 20mph at 48v), and our Geared Motors have been replaced by a 500w version, (approximately 20mph at 36v or 28mph at 48v). The Direct-Drive is now our Heavy-Duty motor and the...
Thankfully, the Pendleton Somerby is an affordable option which, though not as high performing as some pricier e-bikes, offers a chance for a beginner or less serious cyclist to venture into the electric bike world. With a classic, elegant, low step through frame, getting on is as easy as possible. This is to all intents and purposes a city bike, from its look to the mudguards and chainguards that keep your clothes pristine, and the space for a luggage rack.
Come for the price, stay for the awesome. The August Live! LS is one of the lower-cost e-bikes you’ll find. What it lacks is gadgets it makes up for in flare and retains just what you need. You won't find a digital display or integrated lights, Instead you get trendy, chopper-style handlebars, a sweet paint job, and a 250 watt motor that is more than capable of tackling steep hills without a second thought. That said, this bike just begs to be ridden on casual cruises down the boardwalk or bike path.
