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.

When looking for the perfect ebike, there are a lot of things to consider. There’s price, weight, capabilities, performance and something that’s hard to quantify: feel. That’s a combination of factors that is affected by the geometry of the bike, its materials, components and other nuances. I took a ride on the crowd-funded Carbo folding bike this week and I’m not sure I’ve ever felt as comfortable on a folding bike in the city as I did on this extremely light, yet powerful ebike.

It’s not as far-fetched as it sounds. In Europe, where the e-bike market has exploded, the European Cycling Union announced that it will create a new racing circuit for e-bikes, including e-road and e-mountain bikes, for the 2019 season. Following suit, the UCI said it will include an electric mountain bike competition in the 2019 World Mountain Bike Championships. Yes, there will be a rainbow jersey awarded to the world’s best off-road e-biker.
Two years worth of research and development may seem like a long time for a mountain bike but when you take a closer look at what Rogue Ridge accomplished in that time period we’re confident you’ll appreciate the work. For instance, each offering hosts a best-in-class 1000-watt motor and 13 amp hour battery to help keep this electric fat bike at the ready whenever you are. Also, with said set of fat tires, any terrain from sand to mud; rocks to snow, is within your grasp. Additional features include a full-color digital display, a range of 29 miles without pedaling, and a tech welded 6061 aluminum alloy frame among many others.
Here is your experience amplifier: Spectral:ON gives you more trails per hour. The RockShox Yari RC suspension fork offers the steering precision and rigidity you need for e-biking with its 35 mm thick stanchions, the RockShox Deluxe R shock absorbs at the rear of any obstacle. For the wheels you can rely on the DT Swiss H1900 Spline wheels with reinforced hubs, freewheel bodies, spokes and rims, specially developed for the E-MTB. Schwalbe tires combine top traction with low rolling resistance. Magura's MT Trail Sport brakes with 203mm front and rear rotors will stop you when you need to. With Spectral:ON 6.0, your greatest adventures are yet to come.

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.
We rode the Vado through the gauntlet, including some of the steepest hills in Palo Alto, and it easily handled everything we threw at it, maintaining a steady 20 miles per hour even on the most daunting of ascents. The bike also handles well on downhills and is both nimble and quick on city streets and paved trails. It’s even comfortable to ride for extended distances, which is vitally important for any bike built for urban settings.
Range is a key consideration with e-bikes, and is affected by factors such as motor efficiency, battery capacity, efficiency of the driving electronics, aerodynamics, hills and weight of the bike and rider.[36][37] Some manufacturers, such as the Canadian BionX or American Vintage Electric Bikes,[38] have the option of using regenerative braking, the motor acts as a generator to slow the bike down prior to the brake pads engaging.[39] This is useful for extending the range and the life of brake pads and wheel rims. There are also experiments using fuel cells. e.g. the PHB. Some experiments have also been undertaken with super capacitors to supplement or replace batteries for cars and some SUVS. E-bikes developed in Switzerland in the late 1980s for the Tour de Sol solar vehicle race came with solar charging stations but these were later fixed on roofs and connected so as to feed into the electric mains.[40] The bicycles were then charged from the mains, as is common today. While ebike batteries were produced mainly by bigger companies in past, many small to medium companies have started using innovative new methods for creating more durable batteries. State of the art, custom built automated precision CNC spot welding machines[41] created 18650 battery packs[42] are commonly used among Do-it-yourself ebike makers.
For Canyon’s first e-mtb the Spectal:ON 8.0 hasn’t simply hit the trail running, it’s power up it in Boost mode. The geometry, sizing and handling are all on point, and details like the adjustable geometry, odd wheel sizes, tyre specific rim widths and short cranks make Canyon a market leader rather than a brand that’s simply playing catch up. With a Fox 36 Fit4 fork the Spectral:ON 8.0 would probably have won the test, the more basic Grip damper never having the measure of Canyon’s superb rear suspension.
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.

Motorcycle manufacturer KTM has long produced bicycles too, but it is in the e-MTB category that the brand’s heritage is really employed. Motocross fans and riders looking to get into e-MTB riding will appreciate KTM’s decision to use a ‘precise’ 29er front wheel and ‘traction rich’ 27.5-Plus rear wheel (MX bikes also feature different front/rear wheel sizing), an approach some other manufacturers have also adopted (e.g. Canyon). The bike is adorned with a solid build kit including e-MTB-specific parts like SRAM’s EX1 drivetrain.
On the 8.0 specifically, Haibike sets you up with the brand new Yamaha PW-X motor. This motor comes standard with a 500 watt hour battery, Bluetooth connectivity, and 80 nm of torque out the gate. The PW-X also boasts the benefit of a dual chainring up front. This means you’ll save some battery if you’re willing to work a little harder and use those gears! Speaking of gears, you’ll get a Shimano Deore XT drivetrain. Pair that with Fox 34 Float Performance front suspension and a Fox Float DPS rear shock (150mm travel) and you’ve got a fully-capable, all-around ride.

This Saturday, Oct. 7, Tim Sway will showcase his “UpTriCycle” at the Greater Hartford Mini Maker Faire. Sway calls the UpTricycle an “off grid, electric, solar charging mobile maker space and carrier for upcycling makers.” He uses minimal tools and footprints in his creation for unlimited potential. On his YouTube page, Sway made a comparison video between a gas-powered trike and an electric trike. He purchased a gas-powered trike first,...
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[58] 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.[59] Reaching VO2 Max, can really help your body as a whole[60]. 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.[61]
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).
Is it sensible to buy an eMTB for well over € 5,000? Probably not. Will you feel cool buying one of these bikes? You most definitely will! These bikes are the supercars and luxury sedans among eMTBs, where the best bike manufacturers in the world have pulled out all the stops regarding design, detail, and technical sophistication. Yet, while some of them tend to remind of a 911 when it comes to handling, others ride like a Hummer H2 – the price tag alone doesn’t predict anything about the actual performance of a bike. In our search for the best eMTB of 2018, we tested the twelve most promising models.
Update: I've had the bike about 4 months now and ride it almost everyday, it is my primary form of transportation, and I have been pleased with it's overall performance, the battery is holding up pretty well and I've never not made it home without juice to spare, the only issue I've had is with flat tires so I wanted to highly recommend putting green slime in the tires, you do not want to have to deal with getting the back tire off for a flat, but other than that the bike is running great, as others have said it is a little less powerful than you may expect but I am very satisfied with the build quality and quality of components. For saddle bags I got the type of bracket that wraps around the seat post and saddle bags meant for that kind of bracket and they have worked well for me, so I can carry my shopping and groceries easily on the bike now . http://www.amazon.com/gp/product/B0030RS5CA?redirect=true&ref_=cm_cr_ryp_prd_ttl_sol_18 http://www.amazon.com/gp/product/B00K6CEPGM?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s01

In response to customer questions about the display, we posted a video detailing the basic setup of the LCD during installation of the kit. You will need to adjust the settings for the motor type, wheel size, and battery voltage in order to match your specific kit.  Detailed instructions are available in the E-BikeKit manual, E-TrikeKit manual and LCD Quickstart Guide
The BH EVO High Performance Urban electric bikes incorporate the “TS System” which fully integrates the battery in the frame and was groundbreaking when launched giving rise to a whole new style of eBikes. The Pro model electric pedal assist bikes include a compact and removable central LCD display, and a new ergonomic and highly functional remote control. See the EVO e-bikes...

And let’s not forget the economic advantages of owning an e-bike. The annual cost of running a new family car is, on average, about $9,000 per year. Running an electric bike costs around $400 per year. And while filling a gas tank costs around $30, recharging an electric bike battery costs only about 50 cents. A tank of gas may get you further, but not 60 times further!
For many bikes, battery range is more important that total power (because they're all pretty powerful). You want a bike that delivers a range long enough for your rides at the power levels you want. Most e-bikes will have three to five levels of assist kicking in anywhere from 25 percent of you pedal power to 200 percent boost. Consider how fast the battery takes to recharge, especially if you'll be using your bike for long commutes.
It’s probable that GM was hoping for more press for its announcement of the same day as Musk’s interview going live, that it had actually built and was going to sell a pair of electric bikes. It launched a $10,000 naming contest. The bikes were built in-house by GM, including engineers who had worked on the Bolt. The Director of General Motors Urban Mobility Solutions, Hannah Parish said:
For an overview of Stark Drive Electric Bike, its features and our story click above. Our passion for biking and our determination to take electric bikes mainstream have driven us to create the world’s most affordable electric bike. As technology improves, so will Stark Drive with the caveat that we will always offer the most affordable electric bikes in the world.
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.[9] 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.
