   RELAY FEATURES   



Two Bikes In One
Full of modularity, the Relay can be ridden with the battery installed and powered, or removed, which transforms it into a regular mountain bike. Its versatility allows you to take it on a road trip where your plans include riding in areas that are legal for eMTB's, and also areas that do not allow eMTB's. The tool free battery door allows you to remove and reinstall the battery in a matter of seconds.


LIGHTWEIGHT AND PURPOSE BUILT
Starting at 42.5lb/19.27 kg with the battery and 37.5lb/17.01kg without the battery, every Relay is purpose built with components to be ridden hard.

Relay Regular vs PNW


RELAY VS RELAY PNW
The Relay and Relay PNW share the same frame. The lower shock flip chip adjusts the geometry to compensate for a 27.5" or 29" rear wheel. Both Relay and Relay PNW have the ability to be run at 160 or 170mm travel front and rear, dual 29 or mixed wheel. Riders can choose the Relay with dual 29 and 160mm travel for a more lightweight, trail bike feel, or chase their burly trail dreams with the heavy hitting Relay PNW with 170mm travel and mixed wheels. The Relay is purpose built to be ridden hard and comes equipped with a component spec for doing so. Making both the Relay and Relay PNW two of the lighter, heavy hitting eMTBs on the market.


Relay Regular vs PNW


FAZUA RIDE 60 MOTOR
The lightweight 60Nm Fazua Ride60 drive unit weighs 4.3lb/1.96kg. The minimal drag and power to weight ratio provide the magic when not riding with power. As you begin to ride beyond the speed cutoff you're not penalized when continuing to push beyond the assistance like that of traditional eMTBs. The 430Wh battery, 60Nm torque, 250 watts continuous power, 450 watts peak power, and overall bike weight work harmoniously together. This all equates to an experience that exceeds what you might expect from its numbers.

Relay Fazua Ride 60 Battery 430wh

FAZUA RIDE 60 BATTERY
The 430Wh battery weighs 4.85lb/2.2kg. It is easily removable via the tool free battery door underneath the downtube. The battery is charged off the bike, which is a bonus for customers with challenging bike storage and charging situations. The tool free battery door makes this hassle free, and it greatly simplifies the frame and door interface making it lighter and more durable.




FAZUA RING CONTROLLER
The simple and ergonomic ring controller adjusts modes with a gentle nudge up or down. Pushing it up increases the power level, pushing it down decreases power level, pushing inward will activate walk mode. Holding the controller up for 2 seconds from any assistance mode will activate a boost mode, giving you peak system power output for roughly ten seconds.



LED HUB
The sleek display on the top tube consists of 5 led lights to give you an indication of power mode and battery life. The Relay has three power modes designated by different LED colors. Breeze mode (Green) is very functional in many situations, and is custom tuned by Transition to use in varied terrain, not just riding to the trailhead. River mode (Blue) is preset to match the amount of energy you are delivering to the pedals. If you're soft pedaling it delivers a minimal amount of assistance. If you're hammering it will give you as much available assistance it can, which provides a very intuitive experience and range management. Rocket mode (Pink) provides maximum power to help you tackle steeper climbs and challenging terrain, it will reduce your range but packs quite a punch.

FAZUA RIDE60 APP
The Fazua Ride60 app pairs to the Relay via bluetooth technology. The Relay comes equipped with our well thought out profile, but you are able to fully customize your settings in all assistance modes. With Max Power and Support Relation you are able to set the maximum mechanical power output and torque in each mode. Support Relation allows you to adjust how much assistance you are given in relation to how much force you apply to the pedals.

Ramp Up allows you to adjust how responsive the system delivers the assistance in each mode. Whether you're an experienced rider looking for the most responsive and powerful setup, or someone who values more distance out of your rides, the app provides a comprehensive array of adjustments to tune your ride to your liking.
