The LT or long travel line that Haibike is one of the most interesting developments in electric mountain biking in quite some time. I’ve chosen the FullSeven LT 4.0 because I wanted to show you another quality, low-cost option. The FullSeven line is built a little less aggressively than the AllMtn series, but still functions as a great all-around mountain bike for those riders who want to hit fire roads, and maybe the occasional single-track trail. The coolest thing about the LT line is that it costs exactly the same as the standard FullSeven line that comes with 120mm of travel. You can upgrade to 150mm on any FullSeven bike for no extra cost.
E-bikes remain a subject of controversy in mountain biking circles. You may not be able to take one on your favorite singletrack right now, as most non-motorized trails prohibit them. However, things have been tilting in a more permissive direction. Most recently, IMBA, the sport’s largest public advocacy group, shifted its stance to support allowing access for some pedal-assist e-bikes (those that top out at 20 mph) on some trails. With every major manufacturer making e-mountain bikes, more access is likely only a matter of time. “In a few years, people will realize that electric mountain bikes have no more trail impact than a regular mountain bike,” Benjamin says.
Stop and go with care. Because you’re heavier and faster, it will take longer to slow down and stop. Squeeze your brakes well ahead of intersections. Remember that the bike will accelerate faster than normal, so don’t start pulling out into traffic until it’s fully clear. Also, because the bike has some heft, you may feel wobbly the first few times you get going or slow to a stop. Practice mounting, dismounting, and stopping in safe places before hitting heavily trafficked roads.
Duke Eco-Marathon Team using an Electric Bike Technologies hub motor for the 2014 Shell Eco-marathon. The E-BikeKit motor provides optimal space saving because it does not require a chain (this makes it great for converting road bicycles to electric bicycles, which is what it is designed to do) but we hope to determine if it provides us with a better overall vehicle efficiency than our outboard motor.
Electric mountain bikes (eMTBs) are relatively new on the scene and mountain bikers are freaking out. “They shouldn’t be allowed on our trails.” “They are going to ruin the sport.” It reminds me of when the first mountain bikes started popping up on trails and hikers were panicking with visions of crazed bikers running them over. Well, their fears never materialized and mountain bikes have become popular tools for exploring the outdoors responsibly.
With 170mm travel, aggressive angles and Shimano’s superbly calibrated STEPS motor, the Focus Sam2 is an enduro bike with a built-in shuttle. With the bolt on TEC pack you really can climb to new heights, but without it the smaller capacity internal battery means you need to be ultra economical with your energy use. It’s also frustrating that the internal battery can’t be removed easily for charging. By far the biggest frustration with the Jam2 though is that the sizing isn’t very generous and standover clearance is limited. It’s still a great e-bike, but when you’re spending this much money, you can afford to be fussy.
It’s important to note that because this is an electric bike, not all trails are legally accessible. You’ll need to check with the federal, state, or local land management agency in charge of the trails you want to ride to see if it’s possible. You may also face some resistance from holier-than-though cyclist types. Those guys are best avoided anyway, and the glowing LEDs on the down tube should at least help you identify them quicker.
Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and thermal protection. Bikes with a pedal assist function typically have a disc on the crank shaft featuring a ring of magnets coupled with a Hall sensor giving rise to a series of pulses, the frequency of which is proportional to pedaling speed. The controller uses pulse width modulation to regulate the power to the motor. Sometimes support is provided for regenerative braking but infrequent braking and the low mass of bicycles limits recovered energy. An implementation is described in an application note for a 200 W, 24 V Brushless DC (BLDC) motor.
A good hardtail can be your answer to both the perfect trail bike and the perfect on-road bike. Their lighter weight also means a faster ride off-road. Haibike offers a full range of 27.5 and 29er wheel size bikes for trails and cross riding. The XDURO and SDURO lines mean a selection of drive systems and a range of power that only Haibike offers.
China has experienced an explosive growth of sales of non-assisted e-bikes including scooter type, with annual sales jumping from 56,000 units in 1998 to over 21 million in 2008, and reaching an estimated fleet of 120 million e-bikes in early 2010. This boom was triggered by Chinese local governments' efforts to restrict motorcycles in city centers to avoid traffic disruption and accidents. By late 2009 motorcycles are banned or restricted in over ninety major Chinese cities. Users began replacing traditional bicycles and motorcycles and e-bike became an alternative to commuting by car. Nevertheless, road safety concerns continue as around 2,500 e-bike related deaths were registered in 2007. By late 2009 ten cities had also banned or imposed restrictions on e-bikes on the same grounds as motorcycles. Among these cities were Guangzhou, Shenzhen, Changsha, Foshan, Changzhou, and Dongguang.
A couple of days ago I went out with my 16yo son on our regular bikes. I soon realized that I can, at 52, no longer keep up with him and pushed myself way beyond what I should have. When we got home I seriously thought I was going to have a heart attack and had to lie down. I was very upset as it dawned on me that as my son got faster and faster I would get slower and slower and that meant I would hold him back on our rides. I decided to investigate and went online to see what was available to help me. I had never heard of Pedego but on a search a Pedego store came up that was a few miles from my home in Fort Worth, TX. I called and spoke to owner Vicky. I asked what time the store stayed open till and she said 5pm. I said j worked until 5pm and she immediately volunteered to stay open later for me to go down to the store. I arrived at 5.30pm and by 5.45pm after a test ride I had purchased my brand new Ridge Rider!! WOW! What a spectacular machine! I drove home perhaps a tad faster than I should have and my son and I went out for a ride. We did the same ride from a couple of days earlier and although I broke a sweat I got back home and felt great! Thanks to the amazing torque of the APS and buttery smooth gear changes I managed all the hills and slopes with ease and saved the flats for actual pedaling under my own steam. Thanks Pedego, you might just have saved my life!!
There are various kinds and classifications of electric bikes on the market, but the more common type is the Class 1, or pedal assist, bikes which have motor units that are activated by pedaling and are limited to lower speeds. In the US, Class 1 electric bikes, the type tested and reviewed here, are limited to a top speed of 20 mph and their motors are designed with a speed governor to regulate this. These types of e-bikes resemble modern mountain bikes, but they have significant battery packs and small motor units integrated onto and into the frame design. The e-MTB pedal-assist motor is typically built around the bottom bracket and provides varying levels of pedaling "support" directly into the drivetrain while the cranks are turning. Most drive unit systems offer several support settings that provide pedal assistance between 25% and 100% of the user's pedaling input.
I always felt GM should have taken a similar strategy as IBM did. Get rid of the manufacturing and focus on the service. In IBM’s case, it was a logical choice. But for a carmaker, switching to service only is foreign territory. GM has a lot of might in its manufacturing power and its global presence, now streamlined to a few brands. However, most of its sales are still gasoline SUVs, CUVs, and pickup trucks, as with other major OEMs. How much is it really focusing on its electric mobility path, including the addition of folding electric bicycles?
The first regularly produced device resembling the modern bicycle was unveiled in 1818. It was called the Dandy Horse. The two-wheeled ride-on Dandy Horse was the brainchild of German inventor Baron Karl Drais, and it featured a handle bar, a padded seat, and two inline wheels of nearly equal size. What it did not feature were pedals; this was a "running machine," thus its name in German, Laufmachine. The Dandy Horse saw only a flicker of popularity, and was largely an historical footnote within a handful of years, though its design is nearly mimicked in the child's balance bike of today.
What exactly is an electric bike? How can they be used for transportation and why do they make financial sense? These are some of the questions my site http://electricbikereview.com and this channel aim to help you answer. This particular video provides an overview of the Easy Motion Neo Jumper ebike and then follows me on an actual commute to work in Austin Texas.
Because e-bikes are capable of greater speeds for longer periods of time than standard bikes, you want extra control. Wider tires provide traction and some bump absorption with little penalty. You also want strong brakes to slow you (and all that extra weight) easily. It's worth looking at the quality of the brakes and investing in bikes with better ones if you can.
