My left crank arm came loose and seems to have damaged the square bottom bracket mount. I assumed the bottom bracket was just a standard square taper, but noticed it says “8fun” on it. However, I can’t seem to find an 8fun bottom bracket available online, so I can’t figure out what part I need—I suspect there is a something obvious that I’m missing. Any ideas to get me back on the road? Thanks all.

eMTBs appeal to a very broad audience, so in practice, the same model is used in very different ways. A final rating according to school grades does not do justice to the individual character of the bikes and doesn’t provide a sufficient system of orientation for new buyers (which is exactly what we aim to do). For this reason, there is a separate article for each bike in the group test; in each article we detail the most important points, informing you comprehensively about the bike’s strengths and weaknesses and the ideal type of riding it is suited for. We also have five-star ratings, which provide condensed snippets of information about the character of the bike for a quick and easy overview.
I know that this topic is new and still contentious, but the community needs to be talking about it because it isn’t going away. The weather up here in Seattle is rainy and cold (no surprise there), so I haven’t ridden my new eBike except around the block to make sure it worked. I can’t wait to hit the trails (legally or illegally). Expect a follow up comparing the eMTB to my other mountain bikes both in how it performs and the feeling I get from riding it. I never thought I would be riding an eMTB, so trust me, I won’t hold back.
Many years of experience have clearly shown that it isn’t possible to make a universal and realistic estimate of an ebike’s range. The range of an eMTB depends on countless factors such as the support level, terrain, rider weight, environmental conditions, and cadence. Those who demand a lot of power from the motor consume a lot of electricity. If you want to travel far, you’ll have to save battery power. Read more about this topic in our article The truth about lab tests.
Me: I had a total of seven knee surgeries over 14 months, and man, my fitness took a beating. Getting back on a bike was both liberating and frustrating. I just can’t go as fast, or as far, as I used to. But, you don’t have to fall victim to a flesh-eating bacterial infection during routine a ACL reconstruction to find the idea of an electric mountain bike appealing.
The environmental effects involved in recharging the batteries can of course be reduced. The small size of the battery pack on an e-bike, relative to the larger pack used in an electric car, makes them very good candidates for charging via solar power or other renewable energy resources. Sanyo capitalized on this benefit when it set up "solar parking lots", in which e-bike riders can charge their vehicles while parked under photovoltaic panels.
As a counterbalance to the cute utilitarian bikes above, the Specialized Turbo Levo FSR Comp is a big, bad, and burly mountain bike. With 27.5-inch wheels, massive 2.8-inch tires, 150mm of travel in the front and 135mm of travel in the rear this bike is made to shred. The Specialized 1.3 Rx Trail-Tuned motor is designed specifically for off-road riding and features a double freehweel design that disengages the gear box at top speed to reduce friction while ripping downhill. The low center of gravity and stout parts make this one a relatively nimble handler that is ready for the rowdiest downhills.
In the pursuit of speed, all trails lead to Camber. We designed it to be the ultimate speed-loving trail bike, which means that having equal efficiency both up and down the trail is an absolute must. To make sure of it, Cambers feature our fully active & independent FSR suspension with our Position-Sensitive Brain technology. So if your rides see you going big and going fast, the Camber is tailor-made for you.
With more and more compelling reasons to experience the benefits of e-bikes, we’ve put together this special issue packed with information on how to get the most from an e-bike, a guide to the main motors and batteries and a showcase of the latest models on the market. So read on, watch the accompanying videos on our YouTube channel and book a test ride to try one for yourself. We guarantee you’ll be hooked.
But if you’re coming back from injury, looking to ride more miles in a shorter period of time, or just ride further without getting exhausted, then the Turbo Levo is just amazing. This bike is the great equalizer. Some may see that as a negative, lowering the sport’s barrier to entry, but we think more people on bikes can only be a good thing. It will make returning to mountain biking after the birth of a child, an injury, or a stressful period at work much easier. Life happens, the electric assist bikes like this Turbo Levo will help more people ride more often.
Controllers for brushed motors: Brushed motors are also used in e-bikes but are becoming less common due to their intrinsic lower efficiency. Controllers for brushed motors however are much simpler and cheaper due to the fact they don't require hall sensor feedback and are typically designed to be open-loop controllers. Some controllers can handle multiple voltages.
Automated Transit Networks (ATN), and the small-vehicle subset of Personal Rapid Transit (PRT), are emerging technologies that can help solve the related problems of congestion, dependence on foreign oil, and planetary climate disruption. ATN/PRT offers clean, quiet, responsive public transit with automated non-stop service available 24 hours a day. In addition to these service benefits, PRT costs far less to build and operate than other transit options ¯ and is safer than walking and cycling on nearby busy streets.
After you decide which style of e-bike you want, consider the class. In the US, there are three classes defined by the type of assist and how fast the motor will propel you. Most electric bikes sold are class 1 or 3. Class 1 bikes have a motor (max 750w) that assists while you're pedaling, up to 20 mph. Class 3, also known as “speed pedelec” can also have up to a 750w motor, but it can assist you up to 28mph. Both of those are allowed in most states and cities without license. Class 2 have throttles that don't require you to pedal to get a boost. They're allowed on most streets, bike lanes, and paths, but less popular than the other classes and not covered much here (because we still love to pedal and the greater distances pedal assist bikes can cover).
The environmental credentials of e-bikes, and electric / human powered hybrids generally, have led some municipal authorities to use them, such as Little Rock, Arkansas with their Wavecrest electric power-assisted bicycles or Cloverdale, California police with Zap e-bikes. China’s e-bike manufacturers, such as Xinri, are now partnering with universities in a bid to improve their technology in line with international environmental standards, backed by the Chinese government who is keen to improve the export potential of the Chinese manufactured e-bikes.
On mine I got the Topeak front and SKS rear mud guards, an Axiom rear rack, front and rear lights. They didn’t have a headlamp with the lumens I wanted, so Tommy the owner went ahead and ordered one for me! He was always available for any question I may have had through his mobile phone, and updated me with pictures showing me different possible setups to see if I would like it.
Functioning as their premier product, the HPC Revolution took over two years and five prototypes to get right. What’s left is a hand-welded electric mountain bike made right here in the United States featuring a 6061-T6 aluminum frame that weighs only 13 pounds and power levels upwards of 6,000W making it capable to reach speeds of 60 mph. You’ll also find its 203mm travel RockShox Boxxer World Cup Fork come in handy while off-roading as well as its Magura MT7 quad piston performance brakes when traveling at close to highway speeds.
Getting an e-bike can dramatically increase how often you ride, according to a recent survey of nearly 1,800 e-bike owners in North America. Beforehand, 55 percent of respondents said they rode daily or weekly. After buying an e-bike, that number soared to 91 percent. It makes sense: Even if you’re super fit, you still get tired (likely from training or racing) and remounting your bike can feel like a chore. If you have an e-bike, you can continue riding while giving your knackered legs a bit of a break. You can also go faster, which makes biking for longer trips more attractive, even when you’re pressed for time.
An electric bicycle, also known as an e-bike, powerbike or booster bike, is a bicycle with an integrated electric motor which can be used for propulsion. Many kinds of e-bikes are available worldwide, from e-bikes that only have a small motor to assist the rider's pedal-power (i.e., pedelecs) to somewhat more powerful e-bikes which tend closer to moped-style functionality: all, however, retain the ability to be pedalled by the rider and are therefore not electric motorcycles.
