For those who may be unfamiliar, Burning Man is an annual gathering in the Black Rock Desert of Black Rock City, Nevada. The event, which began in 1986, spans from the last Sunday in August to the first Monday in September. There are no corporate sponsorships, advertisements, or entertainment at the event. Individual participation is what's key to making the event special and memorable. Although the participants are given a...
A letter from Casey Evans to Electric Bike Technologies, makers of the E-BikeKit™ electric bike conversion kit system. This one of kind adaptive electric stroller was designed by students from California State University-Sacramento using two 500w direct-drive hub motors controlled by a single E-BikeKit system. Thank you for enabling me to take my daughter hiking! My name is Casey Evans and my daughter, Montel, was born with a very rare...
China has experienced an explosive growth of sales of non-assisted e-bikes including scooter type, with annual sales jumping from 56,000 units in 1998 to over 21 million in 2008, and reaching an estimated fleet of 120 million e-bikes in early 2010. This boom was triggered by Chinese local governments' efforts to restrict motorcycles in city centers to avoid traffic disruption and accidents. By late 2009 motorcycles are banned or restricted in over ninety major Chinese cities. Users began replacing traditional bicycles and motorcycles and e-bike became an alternative to commuting by car. Nevertheless, road safety concerns continue as around 2,500 e-bike related deaths were registered in 2007. By late 2009 ten cities had also banned or imposed restrictions on e-bikes on the same grounds as motorcycles. Among these cities were Guangzhou, Shenzhen, Changsha, Foshan, Changzhou, and Dongguang.
E-bikes can also provide a source of exercise for individuals who have trouble exercising for an extended time (due to injury or excessive weight, for example) as the bike can allow the rider to take short breaks from pedaling and also provide confidence to the rider that they'll be able to complete the selected path without becoming too fatigued or without having forced their knee joints too hard (people who need to use their knee joints without wearing them out unnecessarily may in some electric bikes adjust the level of motor assistance according to the terrain). A University of Tennessee study provides evidence that energy expenditure (EE) and oxygen consumption (VO2) for e-bikes are 24% lower than that for conventional bicycles, and 64% lower than for walking. Further, the study notes that the difference between e-bikes and bicycles are most pronounced on the uphill segments. Reaching VO2 Max, can really help your body as a whole. Professor Janet Lord of Birmingham University in the UK published a study that looked at older cyclists, ““The study looked at muscle mass, blood cholesterol, their VO2 Max, lung function, and in many of those measures we found they didn’t age! No loss of muscle, their bones were a little thin (but nothing like the general population), their blood pressure didn’t go up.
The box looked rough. Lots of little digs and dents. When I opened the box, the contents were very well packed. Mine did show that it took a good hit to the headset stem as the spacers where shoved and the clear tape was all bunched up and the one spacer was almost at the edge. After taking the tape off, cleaning all the tape residue off everything went together super easy. I used the included multi tool to do most of the assembly. I just needed a wrench for the peddles.
When riding a normal bike through creek crossings, and rock gardens, I typically stop pedaling often to avoid pedal strikes, and to maneuver the bike. This approach is not compatible with the Turbo Levo’s weight. On it, continual pedaling was necessary, but the big tires and well-damped suspension enabled me to roll over obstacles I’d typically try to avoid, with the motor helping me power over them smoothly. To make this constant pedaling possible without pedal strikes, the bottom bracket is moved higher and Specialized has spec’d 170mm cranks that are a tad shorter than normal.
The Shiv TT boasts an aerodynamic frame that observes the letter, but not the spirit, of the UCI's laws on position and frame shapes. Its profile has been refined in our Win Tunnel to take crosswinds in stride, and the wide range of fit options in the integrated cockpit lets riders find a fast, comfortable position for putting out power. Impressively, this is done without causing time-eating instability in tight corners or on technical descents.
What does this mean for anyone with Stark Drive that was backed with greater then a 250W motor? Quite simply, it means that as long as you have not modified Stark Drive in any way, and depending on your local countries regulations (if they differe with this EU Standard) you are now able to use your bike legally in your location no matter where you are in the EU.
The sub has been awesome in giving me confidence, I got a Giant XTC from CL. and was going to order all the parts from Luna's Black Friday Sale. A couple of questions, I will have a bike shop remove the bottom bracket, but I am assuming the Bafang 750 with the 17 AH battery should be an easy install at that point (or is it)? I am thinking of having the bike shop install the motor too and I do the the rest. besides a pedal crank, Allen wrenches etc, what tools will I need? Any top rated videos to watch? Is the speed sensor worth it? What about the half twist vs. full twist vs thumb throttle? Color display,, etc. Since the bike has a 10-speed cassette, will that be good or bad (me thinks good). Any other thoughts or pointers? Should I order the stuff from Aliexpress or Ebay?
The Liv Amiti-E+2 is a low-priced but highly versatile e-bike. It’s just as much at home on the pavement as it is on bike paths and rail trails. But don't feel constrained to groomed paths. Front suspension and 42mm-wide tires mean you can take on off-road detour on your way home from work. Speaking of work, this e-bike makes a great commuter thanks to rack and fender mounts and integrated lights for riding after dark. Internal cable routing and a nicely integrated battery make for clean lines and 9-speed shifters give you plenty of gearing options for whichever type of terrain you decide to tackle. This do-everything bike is great option if you’re riding includes a little bit of this and a little bit of that.
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.
The extra grip a 50lb e-bike normally helps to prevent overshooting corners when on the brakes, and bring pure DH-bike-like fun factor on the steepest trails. This electric Orange, however, rides more like a ‘standard’ enduro bike with a motor, which could be good or bad, depending on your expectations and riding style. It’s built tough and delivers stacks of fun in less time than any regular bike can. Adding a motor hasn’t upset Orange’s superb geometry.
Torque sensors and power controls were developed in the late 1990s. For example, Takada Yutky of Japan filed a patent in 1997 for such a device. In 1992 Vector Services Limited offered and sold an e-bike dubbed Zike. The bicycle included NiCd batteries that were built into a frame member and included an 850 g permanent-magnet motor. Despite the Zike, in 1992 hardly any commercial e-bikes were available.
