Stealth F-37 Fighter now packs a long-range punch

Aspiring Stealth owners can push “range anxiety” aside as Stealth HQ has backed-up the F-37 Fighter’s recent power upgrade with a new, long-range power pack. Real-world test results have already seen the upgraded F-37 covering over 100km on a single charge, sending it deep into the e-bike Holy Grail, where speed comes without comprising battery range.


With battery technology evolving at an ever-accelerating rate, a 40% increase in energy density is now possible, and represents the beginning of a new wave of performance enhancements across the Stealth range, sending it even further ahead of the top-tier electric bike market.


To take advantage of the enhanced technology, F-37 riders can utilise the DC-1 Display’s new “E” mode, a setting which test riders have claimed has increased their range by a further 25%.


Driving the technological progression is Stealth’s obsession with continuous improvement and R&D. “When we’re talking about electronic systems, evolution and development is rampant on a worldwide basis. No company stays ahead of the game by resting on its laurels, which is why the team at Stealth actively enhances their own technology rather than waiting for others to do it for them,” said Stealth’s CEO John Karambalis.


“We know we’re at the forefront of our industry, but that’s not enough, and this is why our products are bolstered by a huge technical investment every year. We consistently act on our riders’ feedback and use our grasp of technology to take our bikes to new heights,” adds Karambalis.


And the investment is paying off, with the F-37 seeing record sales for the first quarter of 2015. “What we’re seeing is a real spike in enduro-style riding, driven primarily by the huge boom in this riding style within the mountain biking industry,” said Stealth’s sales manager Theresa Moolenschot.


“Our F-37 product is positioned nicely to meet the needs of these riders and they’re obviously appreciating this. It’s of course way faster and more durable than an enduro mountain bike, offers infinitely more thrills, and still doesn’t need a drop of a fuel – and this simple, low-maintenance style matters to mountain bikers.”


With around 100km of riding range and a 3.7kW output at its disposal, now is the time for your first F-37 experience, especially if you’re hitting summer in the northern hemisphere. You can request your test ride right here.

    I have been running the new battery in my Fighter for a while now, it really lives up to the hip. Keeping speeds around 20mph and pedal assisting, I saw 62 miles and 1054wh consumed. This new battery still had 300wh left in it. Could have easily went another 15miles or so.
