Are these battery packs compatible with all e-bikes?

The packs are intended for Rad Runner models listed by the vendor; compatibility depends on frame mounts and connector type—confirm with the rental provider before booking.

How much extra range do they provide?

Range varies by terrain and rider input, but the additional pack typically doubles typical assisted range on mixed valley and gravel routes.

Can I fly with these batteries?

Battery transport rules vary by airline; because these use Samsung 35E cells, check airline lithium-ion limits and consult the rental company about transport or shipping options.

What are the pick-up and return times?

All rentals start at 8:30 a.m. and must be returned by 7 p.m.; deliveries and pickups after 9 a.m. are charged at the same price.

Is the pack theft-resistant?

Yes—the removable pack includes a lock to deter casual theft, but never leave valuables unattended and always use a frame lock.

Are there weight penalties?

Yes—the Standard Battery Pack is 7.7 lb and the RadMission 1 pack is 7 lb; add that to your bike weight when planning handling and transport.

Range Extender Rad Runner Max and Rad Runner 3 Plus for Extended E-Bike Rides in Grand Teton | E-Bike | Bike Tour

On a high-clear morning in Grand Teton National Park, electric bicycles cut across sage flats and curved switchbacks, and a spare battery can be the difference between turning back at the ranger station and reaching a remote alpine lake. The Range Extender Rad Runner Max and Rad Runner 3 Plus battery packs are a one-day add-on designed to extend an e-bike outing: removable, lockable packs built with genuine Samsung 35E cells and a visible charge-level indicator. They're marketed as an upgrade for riders who want to explore farther without hauling a heavier bike or worrying about last-mile power.

These packs slip onto Rad Power-style frames and weigh 7.7 pounds for the Standard Battery Pack and 7 pounds for the RadMission 1 pack, a small trade-off for doubling range on mixed terrain. For Grand Teton rides that combine valley roads, gravel service lanes, and short climbs toward trailheads, being able to swap or top up a battery keeps pace steady and preserves your energy for scouting overlooks. Rentals start at 8:30 a.m. and are due back by 7 p.m., so the add-on is optimized for full-day circuits that begin in the valley and push into foothills or along lakeshore roads.

This accessory is notable for practical reasons: the lockable design deters casual theft during stops, the removable cells make air travel or transport logistics simpler, and the integrated charge indicator removes guesswork so you don't arrive at a remote trailhead with zero bars. The product description references Grand Teton itineraries, and the pack is ideal for riders who want to include a detour to Jenny Lake, a loop around Phelps Lake, or a lengthier run toward the less crowded valley roads. The listing also notes that deliveries and pickups after 9 a.m. are charged at the same price, and that this battery is sold strictly as an add-on to a one-day rental.

Though the vendor listing notes a location in Braintrim Township, Pennsylvania, the add-on's intended use is described for Grand Teton explorations. Consider pairing a pack with standard safety gear, helmet, lights, and a frame lock, and plan your route based on elevation gain: the Tetons are granite and glacial in origin, with steep roadside grades that sip battery power faster than flat asphalt. For riders who like to mix aerobic effort with motor assist, the Range Extender transforms a cautious day ride into a confident all-day outing, and it's one of those small pieces of kit that broadens where a rental e-bike can actually take you. Bring a compact charger, a simple multi-tool, and a first-aid kit; communicate your route with someone at your lodging, and respect seasonal road restrictions and wildlife closures while you enjoy extended access to park roads.
