Our Stereo Hybrid HPA 27.5 has turned out to be one of the most popular full suspension e-bikes with cycling magazines and websites; it's completely changed the face of e-mountain biking since we introduced it. The reason for this is as trivial as it is obvious - it's an e-bike that rides in a strikingly similar way to a conventional MTB, more so than any other e-MTB. Whether climbing or descending, the Stereo Hybrid HPA 140 Pro will leave you breathless (but only metaphorically!)
For 2017 we treated the Stereo Hybrid HPA 140 Pro to a frame upgrade. Using Tuned Drive Position meant we could optimise the location of the Bosch drive unit while shortening the chainstays by 20mm. That, in turn, enabled us to tweak our Agile Ride Geometry to give an even livelier, better balanced ride than before. Hard to believe, but true. And, because these changes mean you're likely to be riding faster than ever, we added Boost hubs to keep everything tracking straight and true. Clever suspension design means that, despite its 140mm of four pivot-driven travel, the Stereo Hybrid remains extremely balanced and efficient even under hard pedalling. Truly, a bike for all reasons.
Equipment: The Stereo Hybrid HPA 140 Pro features Bosch's superb CX Drive Unit with 75Nm torque - your guarantee of the best trail ridng experience. The 400Wh battery fitted as standard can be upgraded to the optional 500Wh unit for even greater range. A highly adjustable Fox 34 Rhythm suspension fork, paired with s Float DPS Performance EVOL shock at the rear, tames even the wildest of trails. Shimano XT gears feature a wide ranging, 11-speed 11-46 cassette and a ShadowPlus rear derailleur to hold the chain securely in place, so you'll always be able to find the right gear. Magura's MT4 hydraulic disc brake system provides reliable, powerful stopping power even in adverse conditions. And we built a strong, reliable wheelset from Deore hubs, DT Swiss spokes and CUBE EX25 rims, then shod them with Schwalbe's grippy Hans Dampf tyres for the ultimate in acceleration, grip and durability.
e-Bikes come in as many shapes and sizes as non-powered bikes, so you can have an electric road bike, mountain bike, city bike or general hybrid style. But, there are extra choices for you to make as well, so this is a brief guide to choosing the e-Bike best suited to your needs. For a more complete guide, please visit our Blog post on Choosing Your e-Bike.
Frame design
The primary choice is whether there is a top tube or you have a step-through frame. If you have any limitations in your hip flexibility and find it hard to raise your leg around the back wheel and saddle, then a step-through frame will be the better option for you. Given e-Bikes are heavier than other bikes, a step-through is also easier to handle if you're not very strong.
Battery power & capacity
"How far can I go between charges?" is the most common question, and the answer is "It depends", but here are some useful guidelines. Firstly, you control how quickly you deplete the battery. e-Bikes have power assist settings that you use to control acceleration and the amount of assist. If you choose "economy", it will take longer to get up to speed, and your top-end speed will be lower than if you select "turbo" mode. In addition, most e-Bikes are pedal assist, so you need to turn the pedals, and the more force you put in, the less you consume the battery charge. Finally, hills consume more power than flats, so your route selection makes a difference.
Batteries are rated in Watt hours (WH), and you can use this to compare the expected range between bikes. You simply multiply the voltage (V) by the amp hours (Ah) to calculate the Watt hours. On average, if you didn't pedal at all, each mile of flat travel will consume 15 WH. The e-Bikes we sell all have batteries with 300 - 400 WH, so that is 20 - 27 miles on a flat road with no pedaling.
Motor location and drive system
There are three primary positions for the drive system, the front wheel, the rear wheel and the crankset (to which the pedals are attached). By far the best is the crankset, as it is the most efficient, and it keeps the centre of gravity low. Motors in the wheel hubs are more common, as they are less expensive, and there are offsetting pros & cons for front versus rear wheel. drive.
Throttle or Pedal-assist
Our FreeGo e-Bikes have a throttle, so you can choose to be powered exclusively by the electric motor. Our other e-Bikes are all pedal-assist, which means the motor amplifies your own pedaling. The amount of power added by the electric motor in all cases is controlled by the setting, for example "economy" or "turbo".
