Electric bike pioneer Rad Power Bikes recently launched four new e-bike models. At the same time, Rad announced lower pricing levels overall and support for Class 3 speed with select models going forward. In addition, Rad introduced UL 2849 Certified Safe Shield thermal-resistant e-bike battery technology.

Why the Rad Power Bikes heat-resistant e-bike battery matters

News reports of e-bike fires while recharging batteries have prompted many e-bike companies to pay for expensive UL Labs testing and certification. Rad Power Bikes’ new models are UL Certified to UL 2849 and Rad went further by introducing the Safe Shield Battery, a proprietary design with thermal resistant technology available in both external and semi-integrated 15 Ah battery packs for Rad e-bikes. Qualified recycling facilities can recycle the new batteries.

How the Rad Power Bikes heat-resistant battery works

Rad fills the cases of Safe Shield batteries with a heat-absorbing resin surrounding the battery cells. If an individual lithium-ion battery overheats, the resin prevents the event from spreading to other cells. The resin also protects the cells from collisions and punctures. Rad Power Bikes will also offer Safe Shield Batteries as upgrades for earlier Rad Power Bike models.

New Rad Power Bikes e-bike models

Rad introduced four new e-bikes for preorder, with shipping to start in April 2024. The four e-bikes include two new models and updates for two existing Rad e-bikes: the Radster Trail and Radster Road. The RadWagon 5 is the latest version of Rad’s cargo e-bike, and the RadExpand 5 Plus is the company’s next-generation folding model.

The newly introduced e-bikes are UL Certified to UL 2849 with Safe Shield batteries. All four models have hydraulic disc brakes, turn signals, brighter headlights, and torque sensors for intuitive pedal power assistance response. Rad designed the e-bike frames with a lower center of gravity than previous models, and the new bikes are rated IPX6 water-resistant.

In the past, riders on Rad Power Bikes couldn’t exceed 20 mph because the company limited the bike modes to Class 1 (20 mph with pedal assistance) or Class 2 (20 mph with pedal assistance or throttle). Three new models, the Radster Trail, Radster Road, and RadWagon 5, can switch between Class 2 and Class 3. Class 3 allows speeds up to 28 mph with pedal assistance, although the speed is still limited to 20 mph with the throttle alone.

Juiced Bikes updates the Scrambler X2, one of the original go-anywhere electric bike options
Juiced Bikes has refreshed its Scrambler X2
Right front three-quarter view of a Juiced Bikes Scrambler X2 parked on sand with ocean in the background.

Fun, fast,  and well-built. Those three words come to mind with any new Juiced Bikes e-bike. Juiced Bikes predates most companies in the electric bike industry. Founded in 2009 by Tora Harris, an Olympic high jumper and Princeton University graduate in Mechanical and Aerospace Engineering, Juiced started selling e-bikes in 2010. The Juiced Bikes Scrambler X2 is the most recent refresh of the solidly-built, g0-anywhere e-bike.

Electric bikes need extra power to travel off-road
The Scrambler X2's standard power train has a 52V 15.6Ah UL 2271-certified battery paired with an upgraded 52V 1,000-watt, geared rear hub motor with a 1,300-watt peak output. The motor's 90 Nm maximum torque nearly doubles the motor power of typical e-bikes. The X2's 52V 25Ah electric motor controller, an often-overlooked component that manages system heating and top speed, has a customized tuning algorithm that's firmware upgradable.

Meet the Pi-Pop, the electric bike you never need to charge (because it has no battery)
It's like a regular bike, but better
Pi-Pop battery-less electric bike parked on grass in front of a brick building.

Electric bikes are hot and getting hotter in the U.S. In response, e-bike manufacturers frequently introduce new models, all powered by rechargeable lithium-ion batteries. French manufacturer Pi-Pop breaks from traditional electric bike design by using a power source you never need to recharge.

The eponymous Pi-Pop electric bicycle, now in the third generation, gets riding power assistance from a supercapacitor that charges while you ride. Like most electric cars, e-bikes with geared or direct drive hubs can regain energy on the go from regeneration while braking. An electric motor reverses energy flow during regeneration, directing the flow back into a battery.
