In my previous trips towing the Pebble Flow with the Cybertruck, most of the roads were smooth highways, with just a few short mountain sections. Thanks to Pebble Flow’s powered assist motors, after over 3,000 miles on the road, I can confidently say this: the Cybertruck can tow two miles for every one percent of battery—no problem at all. I’m totally confident about that.
But what about mountain driving?
Last weekend, I went camping with friends at Mammoth Lakes. From San Jose, the fastest route is Highway 120 through Yosemite National Park, then connecting to Highway 395 all the way to Mammoth Lakes. The highest point on Highway 120 is Tioga Pass—9,943 feet above sea level. From San Jose to the top, that’s about 9,500 feet of elevation gain over 215 miles. I stopped once to charge in Groveland.
In total, I used 186.5 kWh, averaging 1.117 kWh per mile. That’s actually really good! Even while towing the Pebble Flow up the mountains, the energy use stayed totally reasonable—pretty much living up to Pebble’s “no range lost” promise.
Now, guess how much energy the Pebble Flow itself used on that trip?
From San Jose to Mammoth Lakes—about 254 miles—it used less than 60% of its battery, around 25 kWh total! Crazy, right? Sounds impossible?
With the old firmware, it would’ve been impossible. Before, Pebble Flow used around 150 Wh per mile, so that same 254-mile trip would’ve taken at least 37 kWh, not counting the massive 9,500-foot climb.
So why did it only use 25 kWh this time?
Here’s the secret: Pebble just rolled out a new firmware update in October that allows recharging even in Easy Tow mode! That means when you slow down, brake, or go downhill, Pebble Flow now regenerates power—just like an EV motor.
This update is a huge deal. It doesn’t necessarily make the Cybertruck tow farther, but it means that when I arrive at the campsite, the Pebble Flow still has plenty of power left for camping in comfort.

之前幾次用 Cybertruck 拖 Pebble Flow 去旅行，雖然會有點小山路，但距離不長，大部份的行程還是在平穩的高速公路上行駛。得利於 Pebble Flow 的自動輔助馬達，經過超過三千英里的旅程，我可以很肯定的說，Cybertruck用1%的電，跑(拖) 2 英里是完全沒有問題的！我信心滿滿！
那在山路上的表現如何呢？週末跟朋友約在 Mammonth Lakes 露營，從 San Jose 出發，最快的路徑是走 120 號公路，穿越整個 Yosemite 國家公園，接上 395 號公路，抵達 Mammoth Lakes。120號公路的最高點是在 Tioga Pass (9943 英尺)，從 San Jose 出發，到達 Tioga Pass 總爬升約在 9500 英尺，行駛距離約 215 英里，中途在 Groveland 充電一次。總耗電量為 186.5 kWh，平均每一英里耗電 1117 kWh。從數據上來看，拖著 Pebble Flow，電耗並沒有明顯的超量使用，符合 no range lost 的承諾。
那你猜猜 Pebble Flow 自己本身耗了多少電？全程從 San Jose 到 Mammoth Lakes，254英里，電耗不到60%，約 25 kWh的電！！很誇張吧！不可能？如果以舊版 firmware 來說，的確不可能，照之前的測試，Pebble Flow 一般路況下，每英里電耗約 150 Wh，254 英里少說也要 37kWh 的電量，更何況要爬升 9500 英尺，電力消耗肯定會超大的。但為什麼反而只用了約 25 kWh 的電呢？細節就在於，Pebble 十月推送了新版本的 firmware，讓在 Easy Tow 的模式下也能 recharge 它的電池。也就是當在減速、煞車或下坡的時候，像一般電車的馬達一樣，Pebble 也會靠慣性的力量來回充電池電力了！這個更新太重要了！這雖然不能讓 Cybertruck 拖得更遠，但我更有信心，在抵達營地時，Pebble Flow 仍保有足夠的電力，能讓我舒舒服服的露營！
