I bought a 2021 Rambo Megatron for nearly $7,000, and at first, it was an incredible machine. After serious heart issues, I needed a bike that would let me continue hunting on my property. My land is mostly hills—50 acres in the Southern Tier of New York, with a top-to-bottom grade of about 14%, which is fairly steep. The bike handled that hill easily, towing me and a 200-pound deer in a trailer at about 14 mph in 2WD. It was absolutely awesome.
On 6/25, with fewer than 100 miles on the bike, it would not turn on. I thought it might be a switch or the display, so I called Rambo, and that is when the nightmare began. The technician told me the original system was garbage and said it made more sense to upgrade so I would be worry-free for a while. I paid the $800, and the parts arrived—wrong ones at first. Eventually, I received most of the parts and had a video call for the installation, which they said was “plug and play.” One piece was missing, so when it arrived, I connected it, finished the installation, and turned on the battery. There was an arc flash, and the battery was ruined. I took the bike to a dealer listed on Rambo’s site. At first, Rambo said I was out of luck because the warranty had expired. However, after the technician working on the bike found an issue with the parts Rambo had sent, Rambo agreed to cover the necessary replacement parts. I still had to pay the technician out of pocket.
After months of parts being shipped back and forth—including three different controllers, two monitors, and different wiring—I finally got my bike back. The factory settings in the new display were wrong again; at one point, it showed a top speed of 153 mph. I decided to let that go since it was not the biggest issue. Excited to try the bike, I rode it to a nearby park and found a small hill about 25 feet long with a 10% slope. I tried climbing it using the front wheel first, then the rear. The bike that used to handle my steep property with ease could not make it up this small hill. After many emails back and forth, Rambo said they would make it right, so I shipped the bike to them. A couple of weeks later, they told me it was ready to be sent back, which cost another $250. At this point, I have about $8,000 invested. I specifically asked whether the bike had been tested under load and was assured everything was fine. It was not. The bike performed no better than before, and now it also has a brake issue.
Then it was back to emailing. The bike was advertised as having two 1,000-watt motors, and I had never questioned that. However, while researching the issue today, I found that the front motor is a Bafang FM G06 750-watt motor and the rear is an RM G06 750-watt motor. WTF? Could the issue be related to the controllers, or was there possible motor damage from the electrical ground fault? Any help would be appreciated.
