Price: $5999.00 | Model Year: 2021 | A premium
A premium "do anything" full suspension electric bike that's equipped to handle pavement, trails, light mountain terrain, rain, shine, day, or night conditions. Available in five frame sizes for optimal fit, the XS and S come with 27.5" wheels and the M, L, and XL come with 29" wheels. Sold through one of North America's largest network of dealers. Trek and Bosch provide excellent support and warranty.
Custom made extra-wide plastic fenders are durable and quiet, very capable in off-road conditions. A sleek and sturdy rear rack provides 25kg (55lbs) of cargo capacity with pannier hangers on both sides and a removable top platform for trunk bags. Puncture resistant tires also feature unique black reflective stripes that combine safety with aesthetics.
Downtube-integrated battery pack and mid-drive motor keep weight low and center. Trek designed a "RIB" battery casing includes a handle for safe removal and transport. The battery doesn't rattle, and it can be charged on or off the bike with the fast 4 amp charger. Peformance Line CX motor is the most powerful from Bosch, but lightweight with a magnesium casing.
Highly adjustable air suspension front and rear with 120mm and 100mm travel respectively. Boost hub spacing and thru-axles increase wheel strength. Extra large 203mm hydraulic disc brakes with heat sinks and alloy cores deliver incredible stopping power. The biggest trade-offs here include the high price, smartphone display (that some may not like), louder motor operation, and increased weight (due to the high capacity battery and accessories).

The 2021 Trek Powerfly full suspension e-MTBs blend European sensibility with modern trail capability for a unique e-mountain bike option.

If I had to think of one common theme that continually came up during our time with the Powerfly, that would be it—too damn fun. Over the months we’ve had this bike, we’ve done it all and it does it all with ease.

Up hill or down, ebikes take an absolute beating, so the new Trek Powerfly 9 has a beefed up the parts package to handle the additional abuse.
Suspension, brakes and tyres are all on point. New battery layout is neat and easy to use.
Could have more generous reach measurements and shorter stems on all sizes.

Built on the bones of the legendary Fuel series, the Trek Powerfly 7 FS is the top-of-the-line e-bike for Trek in Australia. It's got great pedigree, but we didn't love every aspect of its performance
Top notch build quality.
Frame feels indestructible.
Great rear suspension.
Torquey motor with plenty of range.
Will climb anything you point it at.
RockShox Recon fork isn't up to scratch.
Long rear end makes for sedate feel.

An exceptionally capable package which will take you further and faster without the need for a lift pass. Buy if you’d like to scale climbs almost as quickly as descents and aren’t afraid to be a little different
Long wheelbase makes for almost absurd stability, superb mechanical grip from well-matched and supportive suspension, Drivetrain and motor play very well together, components list features plenty of excellent e-bike specific parts
Flimsy tyres are at odds with the rest of the bike, New ‘e-mtb’ power mode perhaps a little too keen for some
