McLaren Joins eMTBs With Interesting Claims
The legendary Motorsport giant has introduced four eMTBs, and two are said to be the most powerful trail-legal eMTBs on the market.
McLaren’s big claim is that two of the models, the Extreme 600 and the Sport 600, are the most powerful trail-legal eMTBs on the market. The other two are built with 250W motors. The claim that they are the most powerful trail-legal eMTBs on the market comes with an asterisk (*). Normally, when someone uses an asterisk like that they include an explanation at the bottom of the page, but we can’t find one on the McLaren site.
Without any deeper explanation from McLaren, it appears that the Extreme 600 and Sport 600 feature motors that produce 600W nominally and 161Nm of torque, with power peaking at 852W.
There’s a lot to unpack in this announcement, some of it awesome and some just curious. With no clarification from McLaren, we’re drawing the conclusion that what they mean by trail-legal is that these are all Class 1 eMTBs that max out their assistance at 20 mph and come with no throttle. They offer four PAS levels: Eco, Trail, Sport and Race.
So what does that extra power get you? Let’s compare it to Bosch’s very desirable Performance Line SX motor. The Performance Line SX maxes out at 600W and 55Nm of torque, so the McLaren motor offers 42 percent more power and nearly three times the torque. What that gives you is better acceleration and more raw climbing power. Compared to many other eMTBs, the McLaren Extreme 600 and Sport 600 will allow a rider to soft-pedal through most terrain. You could climb our infamous Hell Hole all day and not break a sweat, maybe.
Some readers are probably wondering why McLaren would choose to enter the e-bike market with high-end eMTBs. This isn’t exactly McLaren’ first rodeo in cycling. They have worked with Specialized to produce special versions of Specialized’s Tarmac and Roubaix road bikes. These bikes featured optimized carbon fiber layups that yielded frames that were lighter, stronger and offered a more lively ride. There’s a special division of McLaren called McLaren Applied that takes the company’s know-how and applies it to other technologies.
There’s another curious statement on McLaren’s page, that their designers spent more than 1000 engineering hours crafting the carbon fiber frame to Class A surface standards. If you’ve never heard of this, that’s okay. It’s an automotive standard—not one used in cycling—that translates to a flawless surface finish. There are no visible surface imperfections of any kind and the whole of the appearance is, to cut to the chase, impeccable.
The four e-bikes also include an integrated carbon fiber bar and stem that incorporates a relatively large display and a 1550 lumen headlight into a single, swooping component. The full-suspension Extreme 600 and Extreme 250 feature a 160mm-travel fork and 145mm-travel rear suspension, while the hardtails are spec’d with a 140mm-travel fork.
The full-suspension Extreme uses a mullet wheel setup with a 29-in. wheel front and a 27.5-in. wheel in the rear; the Sport goes with 29-in. wheels front and rear. All four bikes will be spec’d with high-end SRAM components.
The McLaren eMTBs are priced as we would expect to see high-end eMTBs from big manufacturers. The least expensive of them, the Sport 250, costs a little less than $8000 and they go up from there. Each model comes in three sizes.
That said, we are surprised that McLaren didn’t release the geometries for the two frames. This is the sort of information that a dedicated bike nerd wants to rabbit-hole. There isn’t a single reputable mountain bike or eMTB maker that withholds their geometry.
Their decision to report the eMTBs’ power-to-weight ratios is interesting, but what most of us want to know is how much these e-bikes weigh in pounds or kilograms.
We can’t verify McLaren’s claim that these are the most powerful eMTBs on the market, but their motor does give us some clues. A motor that produces 600W nominally and 161Nm of torque is well within the current abilities of Bafang and it seems more than plausible that McLaren would have worked with a company currently producing e-bike motors to private-label their motor rather than build a factory of their own. One of Bafang’s current offerings comes very close to the McLaren motor’s performance. The Bafang M615 can be ordered as an OE motor by brands and spec’d on their e-bikes, configured to either produce 750W or 1000W, with torque measuring 160Nm; this may well be the basis of McLaren’s motor, though even if it’s not other manufacturers are free to order it.
Also curious is their boasting of spending 1000 hours getting the surface finish perfect. Cool, but that won’t make this eMTB ride any better than the Ibis Oso or Specialized Levo. Tell us something useful, like what sort of suspension design is being used.
That McLaren will offer only three sizes telegraphs that their production level will be modest. Not cutting tooling for either an XS or XL size will leave some riders out, and not many dedicated riders will want to drop more than $10,000 on an eMTB that doesn’t fit perfectly, which brings back the no geometry issue: What is the reach and stack for each size? If you’re 5 feet 10 how do you know whether to order the medium or the large? No one drops this much money on an e-bike and chooses their size solely based on their height.
More surprising still is their decision to integrate the bar, stem, light and display. We’ve seen multiple examples in the past of companies that were new to the bike industry and launched a bike or e-bike with the display integrated in the stem and sooner or later that display breaks, which means that while it is being serviced the owner either goes without their ride or they are forced to purchase other components in order to ride while the display is being serviced. Adding a light means there are additional opportunities for something to break. And for those who care about their fit, integrating the bar and stem means that you can’t change the rotation of the bar, which is a fundamental part of establishing a good fit. And what if the rider wants a bar with some rise? There’s no way to swap this out. Finally, because McLaren isn’t a bike company it seems likely that at some point in the future—be it three years, five years or eight—they are likely to leave the eMTB business, unlike Specialized and Trek. McLaren’s warranty is two years.
These are impressive eMTBs, but we’d like to know a bit more about them.
