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...
In our head to head range test, the Specialized took the win by travelling 20.6 miles and 3,455 vertical feet, 10% farther than the Trek at 18.6 miles and 3,076 vertical feet, 15% more distant than the HaiBike at 17.8 miles and 3,215 vertical feet, and 17% more than the Commencal at 17.1 miles and 3,100 vertical feet. Each of these electric mountain bikes can take you a long way out on the trail, but the Specialized uses its power the most efficiently and can keep you out to play for longer than the competition.
Nicolas Zart Nicolas was born and raised around classic cars of the 1920s, but it wasn't until he drove an AC Propulsion eBox and a Tesla Roadster that the light went on. Eager to spread the news of that full torque, he was invited to write for various CleanTech outlets in 2007. Since then, his passion led to cover renewable energy, test drives, podcasts, shoot pictures, and film for various international outlets both in print and online. Nicolas offers an in-depth look at the e-mobility world through interviews and the many contacts he has forged in those industries. He particularly enjoys communicating about the new e-mobility technology and what it means to us as a society. Today he focuses most of his writing effort on CleanTechnica, a global online outlet that covers the world of electric vehicles and renewable energy. His favorite tagline is: "There are more solutions than obstacles."
You've gotta get up to get down and one of the purposes of e-bikes is to make it much easier to do so. Since we spend significantly more time climbing than descending, we felt it was important to rate how well these bikes perform when pointed uphill. Climbing on an e-MTB with pedal assist support is somewhat different than climbing on a bike without a motor. These bikes are capable of carrying some serious speed uphill, changing the climbing dynamic with a much faster pace, often tossing finesse out the window in favor of power and momentum. The heavy weight of these bikes and plus-sized tires gives them incredible traction, keeping them planted on the ground, and dampening switches can be left wide open to enjoy the added traction benefits of active rear suspension. Each bike's geometry, handling, and power output all played a role in how well these bikes performed on the ascents, and we had plenty of time to test them while rallying back uphill for more downhill laps.
The new Stumpjumper is the ultimate trail bike. Seriously, the damn thing rides like it’s on rails. It’s the most versatile trail bike we’ve ever made. And yeah, we’re stoked about that, but we’re even more excited about how well it’s tuned to you. We’ve said goodbye to proprietary bullshit, focused on your needs, and made, what we feel, is the new benchmark in trail bikes.
Whether you're riding in the backcountry or racing enduro, you need a bike that's capable and efficient. After all, to ride 'all mountain' necessitates riding the entire mountain. That's why our Enduro line of all mountain bikes, both in 650b and 29er options, come equipped with loads of travel, lightweight constructions, and geometries that can handle themselves on anything from downhill tracks to stomach-wrenching climbs.
Not the best bike but good for what it is. 250watt. not enough power even for small hills on its own and does not do 15/hr even on flat ground. battery looses power when cold but still works. Over all so far, dispite the above I give it 4 stars because it is what you would excpect in a cheap bike and it does work. There is no braket for the headlight tho so be warned you will have to improvise on that.
There are many places in the U.S. where you can legally and responsibly ride e-MTB's, and take it from us, they are a heck of a lot of fun. Check with local land management agencies to find out where you are allowed to use an electric mountain bike before taking to the trails. One thing we do know, e-MTB's can be used on any trails that are legal for motorized use, so we took advantage of the wealth of OHV trails in the greater Lake Tahoe area for our testing purposes and had more fun doing it than any of us expected.
**The eBike uses a quick-release battery system. Lightweight 200Wh Lithium-ion battery packs can be swapped in seconds at the roadside. Each pack weighs just 1.4Kg, so spare battery packs can easily be carried for longer trips. The range that can be achieved from each pack will vary according to the conditions and effort exerted by the rider. Ranges of around 30 miles are normal per each full eBike battery charge. Less fit riders may achieve ranges of 10 miles or less, particularly in challenging conditions like steep hills, strong head-winds or soft terrain. The conditions which affect the range are rider fitness, weight, size and seating position, head or tail winds, gradient, terrain, tyre pressure, what gear is used, number of stop/starts and the speed the bike is ridden.
If you haven’t ridden or even seen a modern eMTB, here is what I have discovered. They are sturdy rigs that come standard with quality mountain bike components including beefy forks and rear suspension systems, strong disk brakes, and a reliable drivetrain. They are heavy but not that far out of the old downhill bike weight class. The distinguishing “e” features are the electric motor at the bottom bracket (some have hub motors), the battery pack, and the handlebar-mounted computer that controls the system. They have adjustable assist modes: off, low (barely helps), medium, and the battery-draining high mode. When everything is put together, they are something to behold.
Electric Hybrid Bikes- As the name suggests, these bikes combine the properties of mountain and fat-tire bikes. They are built to be fast and tough at the same time. They are lighter than electric mountain bikes, so you don’t have to deal with the excess weight when going up hills. You can use the bike to carry heavy luggage or cycle through rough trails.
There are individuals who claim to have lost considerable amounts of weight by using an electric bike. A recent prospective cohort study however found that people using e-bikes have a higher BMI. By making the biking terrain less of an issue, people who wouldn't otherwise consider biking can use the electric assistance when needed and otherwise pedal as they are able. This means people of lower fitness levels or who haven't cycled in many years can start enjoying the many health benefits E-bikes have to offer. 
When I started looking beyond the legal regulations, I discovered something that further disturbed me: the mountain biking community is predominantly anti-eBike and quite vocal about it. Maybe it’s a minority that is louder online, but either way, I was shocked to see that mountain bikers and mountain bike organizations, such as International Mountain Bicycling Association (IMBA), are against sharing the trails with eBikes. While some of the online community spoke up in favor of eBikes, they were outnumbered by hardliners.
I saw an early version of the Carbo and was impressed. Although it looked thin and flimsy — the entire frame looks like you can bend it on a bad curb — it was very resilient and withstood my urban abuse. There are multiple modes, including Sport, which takes you almost immediately up to about 20 miles an hour with pedal assist, a great feeling. The battery is hidden inside the seat post and can be swapped out.
Your embark is more than a bike – it's a healthy alternative to traffic, hills, parking and sweat. 65% of riders use their eBike to replace their car. 66% said that they preferred an eBike because of hilly terrain near work or home. Nearly 75% rode their eBike to different destinations than their standard bike. The Embark brings your destinations closer and expands your world - all with simplicity and reliability.

In our view, e-bikes are approaching a crossroads in concept and design. Heading off in one direction are longer travel, enduro-style e-bikes, which are largely designed for cruising up and then blasting back down. Plotting a slightly different course is the idea of a lightweight model that rides much more like a normal mountain bike, but requires more work from the rider. Of the two approaches, both have their benefits, but it’s the latter that gets us the most excited. Once the overall weight falls into the 16-17kg range (the lightest bikes are currently19-20kg) it’s going to be really hard to tell the difference between an e-bike and a regular trail bike on the descents and the flat, but you get the benefit of a gentle push up the climbs.
Functioning as their premier product, the HPC Revolution took over two years and five prototypes to get right. What’s left is a hand-welded electric mountain bike made right here in the United States featuring a 6061-T6 aluminum frame that weighs only 13 pounds and power levels upwards of 6,000W making it capable to reach speeds of 60 mph. You’ll also find its 203mm travel RockShox Boxxer World Cup Fork come in handy while off-roading as well as its Magura MT7 quad piston performance brakes when traveling at close to highway speeds.
Bicycles featuring pedal power were developed during the subsequent decades of the 19th century, with the most emblematic example being the bicycle we know today as the Penny-Farthing. The bike was named based on the substantial difference in its wheel size resembling the larger and smaller Penny and Farthing coins, respectively. These bicycles were wildly popular among the well heeled upper classes of Europe and America despite their penchant for launching riders head first over the large wheel, not to mention their relative difficulty to mount and dismount.
The Spectral:ON is our most challenging development project to date. With the focus on the essentials, it was our clear goal to design an E-MTB that rides like the perfect trail bike. The result is already award-winning: modern trail geometry, wheel concept with 29/27.5" wheels front and rear, plus Shimano's powerful Steps E8000 drive. With the support of the engine, Spectral:ON expands your horizons: more trails per hour, trying out new ways and pushing the boundaries. You master even steep, technical climbs playfully and enjoy the agile handling and the outstanding smoothness in fast passages downhill. Space for bottle holder, geometry adjustment and lightning-fast battery change? Standard! We've taken every detail into account to give you the ultimate E-MTB driving experience.
E-bikes use rechargeable batteries, electric motors and some form of control. Battery systems in use include sealed lead-acid (SLA), nickel-cadmium (NiCad), nickel-metal hydride (NiMH) or lithium-ion polymer (Li-ion). Batteries vary according to the voltage, total charge capacity (amp hours), weight, the number of charging cycles before performance degrades, and ability to handle over-voltage charging conditions. The energy costs of operating e-bikes are small, but there can be considerable battery replacement costs. The lifespan of a battery pack varies depending on the type of usage. Shallow discharge/recharge cycles will help extend the overall battery life.
