Twice the speed - with half the effort, Optibike has the power. On a test ride in Boulder Colorado, a fit road cyclist was able to climb the notorious Old Stage Road at 10 MPH sitting down with an easy spin on the Optibike. On his ultra light road bike, he had to stand and grind all the way to go 5 mph!!! Twice the speed - half the effort, Optibike has the power.

This bike is designed for hauling. The Yuba Spicy Curry has a combined capacity of 500lbs (200lbs on the front including rider, and 300lbs of passengers or cargo on the back). To help move this weight, you’d expect a decent motor, and the Bosch Performance Line CX delivers. Normally only found on mountain bikes, the 75Nm of torque makes light work of hills, even with the heavy load.
The high quality Drive Units from Bosch eBike Systems are the power behind your eBike – and are designed to be both functional and attractive.

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.[65]


A woman blinded in one eye by Brooks Koepka's wayward tee shot at the Ryder Cup has demanded improvements in spectator safety as she claimed she could have died from her injuries. Corine Remande, 49, who is considering suing organisers after being flattened by the "bullet" shot on Friday,  spared Koepka of blame, saying responsibility was with the Le Golf National marshals. Amid pressure on organisers to tell spectators to stand further away from hazardous holes, Ms Remande said: "I hope that this terrible accident will improve safety for the public." The R&A, which organises The Open next year at Royal Portrush, has said it is already carefully planning viewing areas at the Northern Ireland venue to maximise spectator safety. Ms Remande, from Egypt, was watching the action from behind the ropes when Koepka's wayward drive at the par-4 sixth hole struck her in the face. She said she did not hear any shouts of "fore". "There are many marshals on the fairways and they have the responsibility to give us the information to react," Ms Remande told BBC News. Koepka says injuring Remande will rank as one of the worst days of his life Credit: AFP Launching a blistering attack on Ryder Cup Europe, she said she could have died. "For me, it's finished. I could not speak with you," she said. Earlier Koepka said that he was "all messed up inside", adding that injuring 49-year-old Remande will rank as one of the worst days of his life. "It's a tragic accident, I'm heartbroken," Koepka told reporters at the Alfred Dunhill Links Championship at St Andrews. "It will definitely be the one shot I regret in my career. (The day he found out) was one of the worst days of my life." Ms Remande has been treated at a hospital in Lyon where she used to work as a secretary. She said she was "very angry" that officials did not check on her or visit her after she was taken to hospital. She alleges there was a lack of safety warnings on the ticket and signage around the venue. Ms Remande had travelled with husband Raphael from their home in Egypt to watch the Ryder Cup on the outskirts of Paris. The European Tour said "fore" was shouted several times, and that marshals are not aware of a player's strategy in advance of any shot, especially in matchplay like the Ryder Cup. Meanwhile, bitter recriminations in the defeated US Ryder Cup camp erupted into another row as a non-playing member of the team launched a foul-mouthed tirade about Patrick Reed. Patrick Reed is said to have 'begged' to play with Tiger Woods Credit: PA An anonymous team member was reported as saying Reed "begged to play with Tiger" and is "full of s**t" after the outspoken player claimed he was "blindsided" by beleaguered captain Jim Furyk. The angry exchange reported by USA Today came amid claims the alleged spat between Dustin Johnson and Brooks Koepka stemmed back to the US team's flight to Paris last week.  Golf Digest and French sports newspaper L'Equipe reported that the pair had an argument over Johnson's fiancee, Paulina Gretzky. Koepka yesterday denied the rift,  despite multiple eyewitnesses saying he and Koepka had to be separated during a flare-up after the team's 17½-10½ humiliation at Le Golf National.  
Featuring Bosch’s newest CX Drive motor, the Trekking has enormous torque (that equals acceleration) compared with the rest of the bikes on test. From a standing start the Haibike reaches the 15.5mph European speed limit in seconds. Pair this with mid-sized 27.5in wheels and laid-back mountain-bike geometry, and you have a grin-inducing almost motorbike-like riding experience. This is accentuated off-road, where a rider’s lower average speed is under the motor cut-off point for more of the time, so suddenly the hefty Trekking makes complete sense.

Known for not only their powerful line of mountain bikes and specialty bikes—cruisers to fat—Bulls also has a versatile line of urban models. The Cross E Wave comes as one of their more affordable options at roughly $2,800, but at 20 mph can still range for up to 134 in optimal conditions with everything you’d expect (fenders, lock, lights and adjustability). The entire family of Bulls e-bikes has specifications built for any scenario.
Above all, the Brompton is a lot of fun to ride in urban settings. Its powerful enough to breeze up hills with near zero effort, but feels nimble. As with any Brompton, you probably won't win a half-mile sprint on it, but thanks to the pedal assistance, you most certainly will get off to a flying start. The reason it stands above other electric bikes is that Brompton has worked out how to apply power assistance to your pedalling so it feels natural. It also doesn't feel so much like it's trying to fight you once you reach the maximum, 15mph assisted speed.

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.
The time or distance an electric bike battery will run between chargings is impossible to judge with much accuracy. There are too many variables: terrain, speed, rider weight, bike load (shopping, kids, luggage), and more. However, we can make a few generalizations about an e-bike’s recharge time and overall working life. These generalizations should be used for comparison purposes only.

However, Emu sells a little foldable number if that's your bag. The Emu Crossbar is for  town commuters that require a sweet ride that's backed up by solid Shimano Nexus hub gears and Tektro brakes, which are adequate if not the best on the market. Riding is smooth and easy, with the crank moving sensor doing its best to iron out any gaps in power delivery.
E-bikes can be a useful part of cardiac rehabilitation programmes, since health professionals will often recommend a stationary bike be used in the early stages of these. Exercise-based cardiac rehabilitation programmes can reduce deaths in people with coronary heart disease by around 27%;[55] and a patient may feel safer progressing from stationary bikes to e-bikes.[56] They require less cardiac exertion for those who have experienced heart problems.[57]
As electric bike options continue to expand, more brands are integrating the battery more seamlessly. That makes them look sleeker (and more like a real bike). Batteries are expensive, so make sure there's a good way lock the battery to your bike if you'll be keeping it outside. Overall weight is important. Some battery and motors can add 15 pounds or more to the bike. With assist, you won't feel that much when you're riding, but you will if you have to carry your bike up stairs or lift it onto a bike rack.
