Yes, Jim, it is a significant elevation gain. That's why, in my opinion, unless you want to be sore every night, eBikes are the way to enjoy the park.

I made a lot of upgrades since I last posted. The Runner has: 1) another Rad OEM battery above the rear wheel under the rack wired in; 2) orange reflective trim on the rims, 3) Ergon grips. 

The Rover has 1) bigger pedals; 2) spare Rad OEM battery carried on the rear rack; 3) 35amp controller and display; 4) guard on the bottom; 5) front and rear cargo bags. 6) orange reflective trim on the rims; 7) dropper/suspension seat post. 

The Runner was previously upgraded with 35 amp controller and display, 750w Bafang motor, suspension seat post, better seat, bigger pedals.

I will post a few photos of the bikes soon.

We are looking forward to the ride in the park with family and friends again in a few weeks.

Here is a photo from our trip last year:

we will be leaving from Tellanika going towards Sable pass.

We are planning our second ride in Denali (Mt McKinnely) in July with 7 eBikes. We have two rad bikes. One Runner and on Rover. We will rent remaining bike. This time we are taking a couple extra batteries. I am looking for this groups comments and suggestions on prepping for the adventure.

With 92 miles of road it would be quite an adventure to do the entire Denali park road. Last time we did about 50 miles one way and 100 round trip across three days. The dramatic elevation changes of the road make it a great fit for e-bikes and non athletic riders. Its also a lot of fun going downhill for miles.

I just bought a couple batt trays from Rad Tech support and a couple batteries. Yes the batteries are expensive from Rad but its like power tools in my opinion. Once you have invested in a system its makes sense for me to stick with that vendor if they provide good service and meet your needs. The service rep I ordered from was a little hesitant to sell the batt trays and asked why I wanted them. I wanted 4 but we agreed to 2.

Thank you for your post. I just ordered two battery cradles from Rad. Wanted 4 but they would only sell me two. Maybe because I just purchased two extra batteries? Plan on paralleling the new battery with the existing battery. We see how it goes. Should fit under the rear rack on wife's runner. Not sure where to put on my rover.
