Our testers were a little underwhelmed by a couple of our competitors. The Rocky Mountain Instinct Powerplay Alloy 50 has loads of potential with excellent geometry and trail smoothing rear suspension, but the spec of a wimpy fork and non-aggressive tires detract from its downhill confidence when the going gets steep or rough. The Trek Powerfly 7 FS was our least favorite e-bike to ride downhill, with an even less impressive component specification that held it back and didn't inspire confidence on descents.
Jan, I disagree with your carry as a prime reason/not be looking at e bikes. My primary reason for an e assist is age and medical problems. Carting a heavy bike around, trying to lift it onto a vehicle would not work, and riding from home is not a possibility. I know there are light-weight e bikes out there. Price, within reason, is not a big concern. Need a 2018 update. E bikes are common in Europe, will eventually be more mainstream in the US.
When he was choosing what battery pack to buy from vendors in Asia, he decided to build a custom pack that he would solder together himself from Lithium-Ion cells. When he chooses to ride with his larger battery pack that provides 800 watt-hours, the total weight of the bike increases from 7.66 kg up to 9.90 kg (21.8 lbs). With the impressive marathoner adding some athletic pedaling, the larger battery allows day tours of a distance up to 180-kilometers (120 miles), and climbing over 4000-meters (13,000 feet) in elevation. Says Schiltknecht, “In 2010, I even managed a one-day tour in Valais through the Diablerets [mountains]”.
The F1-trained engineers at William Advanced Engineering assisted with the electrical parts and the result is a 250W motor that provides pedal assistance via the front hub – which is still a very unusual approach. It draws power from a 300Wh battery pack that sits in a bag and goes on the front where the Brompton luggage rack would normally sit. You can also opt for a larger bag that holds both the battery and your spare suit or laptop or whatever.
The bike has three speed modes: low, medium and high. The top speed is about 18 miles with motor only and 25 mph with pedaling. The range you can get out of the motor is about 30 miles, but since you can pedal it just like the traditional bike after the battery dies, there is really no limit to how far you can go. 21-speed gear shift system allows you to be in full control of your ride, and front and rear disc brakes protect your safety. The Ancheer electric mountain bike is also equipped with LED headlight and horn.
How Far Can You Go On A Electric Bike
In theory, an electric bicycle battery can undergo several hundred charge cycles. How much exactly? That depends on the battery type concerned. The way you take care of your battery will also affect its life. For example, if you store your battery somewhere dry and protected from temperature fluctuations, you will keep it longer. In general, with regular use, an electric bike battery becomes less efficient after 3 to 5 years.
