What makes the Momentum PakYak E+ a great bike for the city?
Every good cargo e-Bike needs a powerful motor, but that is just part of the equation. The PakYak is also a bicycle, so it needs to operate like one. Just like its non-electric cargo counterparts, the PakYak E+ is centered around durability, stability, and rider convenience while riding in a city.
- Frame: Momentum used Giant’s ALUXX-grade aluminum to make the frame of the PakYak E+, giving it a very strong build. It features a step-through design, which is a must-have for any good cargo bike. This keeps the bike stable under a payload when mounting and dismounting, or when stopped.
- Cargo Design: Every feature of the Momentum PakYak E+ is designed to make hauling all the cargo you need easier. It includes a rear utility rack that can support two child seats or two heavy side baskets. It also has a front basket, which has a removable base and bottle cage mounts.
- City Compliance: Riding through the city with a ton of weight isn’t easy on a bike. That is why the PakYak is so durable and compliant. A 70mm dropper post makes the bumps of the road easier to deal with. High-volume urban tires prevent flats and add to the compliant nature of the bike. It also includes a kickstand to make sure it stays upright when you get off.
What e-Bike features are on the Momentum PakYak E+?
The Momentum PakYak E+ is a Class 3 electric bike, so you know you are going to get a powerful drive unit. This bike can reach up to 28 mph when pedaling before the assistance shuts off. Momentum makes sure that everything you need to fully control your ride is at your fingertips.
- Drive Unit: The Momentum PakYak E+ uses the SyncDrive Pro motor as its drive unit. Giant teamed up with Yamaha to create this 250 W mid-drive motor. It offers 80 Nm of torque, giving you all the strength you need to move heavy cargo, especially up hills. With up to 360% of pedaling power assistance, all the strain can be taken off the rider in a tough situation.
- Practicality: The bike comes with a 6-Amp high-speed smart charger, so you can always be ready to go. A Shimano Nexus 5-speed internal gear hub is designed to handle high-torque scenarios without skipping gears. There is also a central lockbox compartment which hides a second battery block, allowing you to instantly double your range.
- Smart Tech: The cockpit of the PakYak includes the RideControl screen, which is a 2-in-1 color screen that tracks your speed, battery, and telemetry updates all in one place. The front of the bike has a powerful LED headlight below the basket, helping you stay completely visible.
