BMC SpeedFox AMPBMC is a small Swiss-brand that garnered plenty of attention from the MTB world in 2013 when they announced their TrailFox: a 150mm travel, carbon framed, 29er that appeared around the same time as the Specialized Enduro 29. Last year saw BMC's 'AMP' appear, an electrified version of the acoustic Trailfox, with a top-of-the-range version that dropped in at a staggering €11,999.
The SpeedFox AMP is a shorter-travel, 130mm version which BMC wanted to appeal more to their general customers. The carbon mainframe with its 'Twin Hollow-core Technology' is shared between the Speed and TrailFox brothers, but the top-end SpeedFox has a new carbon swingarm that saves 700g over the bigger hitter and the rest of the components are aimed towards less-aggressive trail riding.

bmc-switzerland.com Frame and Drive The carbon frame is designed along with the rest of the BMC range in Grenchen, Switzerland. The AMP delivers a bold look with its huge headtube junction and massive downtube. The bike's "Twin Hollow-core Tube Design" consists of two complete and connected tubes that run either side of the huge internal battery, from the headtube to the motor/seat stay junction.
BMC claims that their unique design increases the lateral stiffness of the front triangle. The brand feels that many of their competitors' current e-offerings have reduced strength and stability in this area due to their battery mounts. Internal cable routing runs underneath the battery and can be accessed for maintenance.
Shimano take care of the drive with their STEPS motor and their own 500wh integrated battery, which has the charging port, LED charge indicators and on/off button directly in the firing line of mud and water. BMC have attended other details with a custom "Drive Unit Nest" that protects the motor from incoming terrain, they have also neatly located the speed sensor into the chainstay and use a hub-mounted magnet.
BMC continues to use a dual link "Advanced Pivot System" (APS) with a one-piece rear triangle to give 130mm of travel. The carbon swingarm is claimed to save 700 grams over the TrailFox's carbon triangle, but unless you can stump up well over five figures for the LTD, you will have to make do with the heavier, alloy version.
Geometry and Sizing There are three sizes to choose from (Small, Medium and Large). Reach numbers range from 401mm, to 445 and on up to 471mm, which should suit the majority of pilots. The head angle is set at 66º and the seat angle at 74º. The bike features a 35mm bottom bracket drop and 450mm chainstays.
Models There are four different models to choose from. The 'budget' version (with an alloy swingarm) is dubbed the AMP Three and costs €5,499. The AMP Two sells for €7,499. The €9,499 AMP One still sports the alloy swinger. To get the full carbon frame is a serious investment. BMC have outdone themselves with the AMP LTD, which will cost a whopping €12,999 – specced with Shimano XTR Di2, lathered with Kashima-coated Fox suspension and rolling on carbon wheels from DT Swiss.
We headed out on the SpeedFox in the Marittima mud. Though the name Forecaster was printed on the tire sidewalls, the tires proved a terrible choice for the weather. As with all Shimano STEPS-equipped bikes, the power transfer is super smooth and the latest firmware updates to the 'trail' mode continue to smooth out power delivery and give a natural feel, with output based on torque applied to the cranks. The motor is quiet, as is the rest of the bike, which is free from chain slap and battery rattles. The massive downtube genuinely adds huge stiffness between the rider's hands and feet, leading to a positive feel and dependable accuracy.
Personally, being interested in more capable and aggressive bikes, I am looking forward to putting the 150mm travel, Cane Creek-equipped, TrailFox AMP through its paces for a full test later this year. Unfortunately, there is still no news about an updated acoustic Trailfox 29er, which has plenty of followers waiting patiently...
we ride longer bikes than ever, low and slack, light, with almost DH capabilities. In the begining of the trend, that was at the expense of clmbing performance, but we didn't care cause what we enjoy is to go fast a.f. in the downs. Now that has changed, and bikes start climbing great too. Dream bikes, trully.
Let's introduce ebikes then. You end up with some 25kg mofo that handles like a pig in the downs, all just to sweat less on the ups, or be able to do one more lap? Basically the oposite of why modern bikes are like they are.
Can't see the point.
Have you actually ridden a modern eBike?
Because your assumption is the same as a lot of people who have read a lot about eBikes, but haven't actually tried one.
aaaand on with the negative props.....
One thing that I don't get is why these bikes have such a wide ratio cassette. Surely you can get away with less as the motor is doing the work uphill? I would have thought a single speed set-up would do the job; save some weight and clutter from an already very heavy cluttered bike.
Can't believe it's gone under the radar. Way more power than you get from a standard ebike and it'll bolt onto anything. Battery goes in your bag...
I for one am happy to know there will be an option for when my knee finally gives in and I will still be able to enjoy the sport with my buddy's.
Those 250W e-bikes would be boring in flatland though.
But please, oh please, don't try tell me they handle like Bronsons now... Even Sam Pilgrim looks like he's flicking around on shopping kart.
So, do they really handle like a bronson in the downs?
You're a fool
They're not very versatile either as they need a trailer to be brought to a track.
They're hardly flying off the shelves.
I bet KTM dealers are probably selling more eMTB's than eMoto's
1. Quite a lot of MTBers bring their bikes to trails using their cars.
2. Not versatile? Uhm, the issue is an average E-MTBer cannot do anything else on the bike than hold the bars and pedal. They may as well sit on a moto.
3. Annual tax and insurance, in Sweden 5k € price difference gives you at least 10 years.
4. Bans on motos, hm. Depends where you live, in many places you can ride a moto in the woods and nobody can touch you. Just take off the license plates. Breakin´d´LHAW!
People don't buy motos because they cannot manage/are affraid of the power and weight. That will change as soon as moto companies get the finger out of their bum and start producing lighter, less powerful motos, aka off road scooters There's at least one already, it looks like it's made by Ikea and it's called Cake. The man making it, founder of POC just needs to design a better looking package. Right now he is in the Swedish functionalism bubble (even Ikea is now going away from it), but still as aone of pioneers he is getting things moving. I'd personally love a light trials E-moto when I get older.
Niche trolling
KILL IT!! KILL IT WITH FIREEE!!
But then for some people 9000€ is pocket change.
