The Chassis. True to the aircraft manufacturing heritage of ZEV, and in keeping with that heritage, the ZEV Aero line is a light weight tour de force with the Valkyri-E the powerhouse built with every bit of company aircraft skill into a hydroformed aluminum chassis. The Purpose built chassis it the heart of this bike. Purpose built frames are very rare, and only very few manufacturers have attempted to market a bike with the battery built into the frame.
Because of this frame, the ZEV feels perfectly balanced, has the wires and cables concealed (and protected), and does not sport a clunky heavy battery rear rack like most electric bikes that ruins the balance of the bike, especially on a steep grade where they make the bike want to over center lift the front. Exceptional balance is a key feature. Without the weight hanging off the back as on paste together ebikes, and with the battery weight in the chassis angled forward with the weight toward the front of the down tube, the bike balances perfectly in the middle.
The ZEV is beautifully balanced in its design. There is nothing that detracts the eye or screams out electric bike. It is silent in its operation. You can have the bike with or without the large ZEV Electric logo on the bike side if you wish to truly remain not recognized as an Ebike rider.
The battery is the second key. At 48 volts nominal, 60 volt peak, and 12 ah, the battery holds 720 wh (576 nominal). This big battery is also the key to the power delivery, smooth and always there. When the riders of lesser capacity battery bikes, with far less power roll on the throttle, the volts available dive dropping the available power. The ZEV big battery lets you keep rolling on the power in the technical sections or on the street at speed. That big battery on gravel rail trail bike paths has provided over 15 miles on the motor only, and 61 on light assist.
The motor while rated at 750 watts continuous, allows riders to storm up hills with up to 1200 watts peak power. The motor, as in all ZEV vehicles is oil bath lubricated and oil cooled, the only such motor in the entire EBike industry. This is to protect your valuable motor, and to make it run more cool and efficient so it can put out more power longer. The oil in the motor also helps protects you from the possibility of corrosion that can occur in any electric motor and lockup. As in all ZEV, the motor is a large diameter. When you double the diameter of a hub motor, you increase the torque by four. We run the largest diameter motors to stop motor lugging and give you seamless torque for 40 Nm of torque. As much as 40%. The big diameter motor is also part of the range formula. Big diameter motors with high torque do not lug as smaller motors which unnecessarily consumes the amps. The larger OD motor uses its torque to get to speed and the amps back down once a given speed is reached. This allows the ZEV to get more range out of a battery than even bikes with slightly larger battery, and use the smaller battery to reduce the bike weight.
