It seems everyone prefers both Juiced and RadCity E-Bikes. I am having a tough time choosing between two. I currently have a mountain bike and want something new just to kick back and cruise around on. I will not be daily commuting, but will be riding weeknights and weekends, so comfort is key. It looks like both will have deals for Black Friday or Cyber Monday. $999 for the Juiced OceanCurrent and $1299 for the RadCity.
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.
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.
When all was said and done, the Commencal Meta Power Race 650B+ proved to have everyone's favorite e-bike controls. Commencal uses the Shimano Steps E8000 motor and system which features ergonomic thumb shifters, a small but easy to read digital display and a secure and straightforward charging connection. The ergonomic shifter of the Shimano system is better than the electronic buttons found on both the Specialized, HaiBike and Trek. The Commencal's best-in-the-test digital display also proved to be a favorite for its small size and out of the way mounting location, easy to read at-a-glance information, and color-coded support settings information. The HaiBike's Yamaha PW-X motor and system also featured a digital display, but testers thought it was a little too big, displayed too much information, was more challenging to read, and generally felt a little more clunky and less refined than the Shimano system. That Trek Powerfly's Bosch Purion shifter and display unit was easy to read and had a bright screen, but was in a less visible location on the left side of the handlebar. Our Editor's Choice Award winner, the Specialized Turbo Levo FSR Comp 6Fattie scored the lowest in this rating due to the lack of a handlebar mounted display and a less user-friendly charging connection.
All models of the Turbo Levo use a frame made from M5 aluminum alloy, with the motor and removable battery integrated inside. The frame and fork use 148mm (rear) and 110mm (front) spacing. Specialized 6Fattie Purgatory (front) and Ground Control (rear) 3-inch wide tires are laced to 38mm Roval Traverse rims. Rear stays and pivots are beefed up to handle the additional weight (48.5 lbs) and torque, and bridges are added to the stays, over the non-motorized Stumpjumper. The front fork is a RockShox Yari XC with a 15mm thru-axle. The 135mm rear travel is provided by a custom Fox Float Performance DPS shock with automatic sag adjust.
Over several months, our team of four professional mountain bike testers rode each of the electric mountain bikes in our test selection on a variety of trails and terrain in a range of weather conditions. We had each tester ride each of the bikes numerous times, often riding the different models back to back for the sake of comparison. We didn't go easy on them. Instead, we treated them all as if they were our own, putting them all through the wringer to identify their strengths and weaknesses. We scrutinized every aspect of each e-bike's performance and scored them all on several rating metrics, e-bike controls, downhill performance, uphill performance, power output, and distance range. Each metric are described in greater detail below. It is important to note that during our testing our impressions of these e-bikes changed dramatically. Our first impressions didn't exactly stick. It was essential for us to test the different models head-to-head and make direct comparisons to flush out the differences. For example, everyone was initially a little underwhelmed with the Specialized's power and more excited about the Haibike, but after hundreds of miles of testing our impressions changed. We go into more detail on this below.
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.
E-bikes use rechargeable batteries and the lighter ones can travel up to 25 to 32 km/h (16 to 20 mph), depending on local laws, while the more high-powered varieties can often do in excess of 45 km/h (28 mph). In some markets, such as Germany as of 2013, they are gaining in popularity and taking some market share away from conventional bicycles, while in others, such as China as of 2010, they are replacing fossil fuel-powered mopeds and small motorcycles.
