Dropping an electrical drivetrain right into a basic bike is hardly a brand new idea, however it’s nonetheless an endeavor largely reserved for outliers. The automotive electrical ‘crate’ motor business is large—however within the bike world, choices are few and much between, and most electrical bike conversions are one-offs.
That’s slowly altering although. Some time again, Luuc Muis developed a drop-in electrical motor for traditional BMW boxers. Now the Parisian customized store Mototherapy has launched its personal electrical bike conversion, additionally concentrating on the beloved boxer.
Mototherapy is asking the undertaking ‘Experience Mercury,’ and that is their prototype, the ‘R01.’ It makes use of a basic BMW R75 as a basis, with many of the authentic bike left inventory (albeit rigorously restored).
“Our major objective is to breathe new life into bikes with character,” says firm founder Jean-Marie Raymon. “This focus has led us to position performance on the middle of our issues. We’re not fascinated about making a showroom curiosity; we intention for a aware and helpful enhancement.”
Making the most of the BMW R75’s versatility, the Experience Mercury staff has designed a full drivetrain that merely tucks into the chassis the place the OEM engine, transmission, and airbox normally sit. It’s just about a plug-and-play system, with no body mods required to make it work.
The motor itself peaks at 20 kW, sending as much as 340 Nm of torque and 30 hp to the again wheel. The present most vary is 150 km [93 miles], with a six-hour cost time through the onboard 1.8 kW charger. (Plans for a quick charging resolution are at present within the works.)
The entire requisite components are packaged into bespoke aluminum housings, with metal used for structural parts. Two of the bike’s 4 batteries are housed in finned casings that mimic the boxer’s iconic cylinder heads; one other two sit additional ahead. The motor is housed the place the transmission was once, and is related on to the BMW’s authentic driveshaft.
As a result of the whole lot has been designed in-house, the structure is continually evolving. Experience Mercury already has a second-gen design that locations the ‘cylinder heads’ somewhat decrease and contains extra air flow. Numerous choices for the entrance engine cowl are within the works too.
The R01 is only a proof of idea—which is why it makes use of Experience Mercury’s prototype ‘engine block’ design, and why a lot of the remainder of the bike continues to be authentic. The objective is to indicate that an electrical drivetrain could be retrofitted to a classic bike with out having to reimagine the entire machine.
The one components which were upgraded, aside from the apparent, are the headlight’s internals and the digital dashboard that hyperlinks to the motor’s controller. Proper now, the OEM gas tank is simply an empty shell—however the crew is engaged on changing it right into a space for storing, or a spot to bundle an upgraded charging port.
The entire bundle received’t be obtainable as a ‘crate’ system fairly but (though the potential of promoting a DIY package in a while hasn’t been dominated out). As an alternative, Experience Mercury will construct you a whole electrical BMW R75 for the tidy beginning value of €29,500 [around $31,233]. Pre-orders for the R01 open subsequent week, with the primary machines anticipated to ship within the second quarter of subsequent yr.
Every construct features a full refurb of the donor bike, plus numerous customized choices. “With all of the care we’ve put into the design and growth of our module, it was unthinkable that machines bearing the Experience Mercury title wouldn’t obtain a full makeover,” says the corporate’s different co-founder, Cédric De Azevedo. “Our method to retrofitting goes far past a easy engine conversion.”
However does it make sense to yank a BMW R75’s motor out to affect it? If that motor is blown (which is admittedly uncommon for outdated airheads), then why not?
In accordance with Experience Mercury’s stats, retrofitting a motorcycle or automotive with an electrical powertrain is as much as 50% extra environmentally pleasant than manufacturing a model new electrical automobile. If it’s important to go inexperienced, this certain is an aesthetic solution to do it.
