Built Rambo Tough

The Open Box Rambo Cruiser is the perfect entry level electric bike for someone who is just getting started with the same GREAT warranty! The new 500W TruckRun motor in conjunction with the 7-speed derailleur creates a good balance of speed and climbing ability. The bike can be used on pavement as well go off-road with ease. The Cruiser works with many of Rambo’s great accessories including front and rear rack, front suspension fork, and fenders allowing the rider to customize the bike to fit their needs.

Our Battery

Rambo’s external battery packs utilize the power of lithium ion cells.  This reliability ensures your bike will be ready when you are, whether it is hunting, weekend riding or daily commuting. The easy slide on/off design allows for quick and easy removal for charging or storage. Rambo’s external battery back offers a max distance of 35 miles!  Not all batteries are equal. In fact, not even close. Many e-bikes that are advertised on the market today at a certain amp hour fall very short. Real life tests show Rambo outperforms again and again! Don’t be fooled for less the than best!

    All I can tell is that it was a demo or floor model. Looks and rides brand new with no issues! Glad I saved some $$…

    I bought this as an open box/demo. I couldn’t tell that the box had ever been open or that the bike had ever been demo’d. Mine is silver, but it is a matte color and not shiny, this suits my preference.

    I have added fenders, a rear rack and large basket. While the bike does fine over flat areas it does struggle on steep inclines. Since I ride steep inclines, I decided to take a chance and see if the Lekkie chain ring would fit. It does!! I currently have the Lekkie 28T HD chain ring installed. It does require the use of a Lekkie spacer. I removed 7 links from the chain and all gears work. I now have to be careful in first gear on an incline the front wheel will come up. I have a 36T Lekkie on order as well. That may be the ticket for me. The truckrun motor appears to have the same chain ring mount up as the Bafang HD motor.

    This bike now has plenty of torque for me on steep inclines.

    Awesome bike and a super deal!

    I bought the Cruiser Open Box and have had it a few weeks. It came packaged as a new bike. I couldn’t find any flaws. This is my first ebike and so far it checks all the boxes for riding some utility easements and mountain bike trails just to test it out for hunting. I have added the suspension forks, mud shovel fenders, and back rack to connect game cart. I’ve rode it quite a bit on the road with no assist. On trails and such mostly in pedal assist 1. Battery life seems it will be fine for where I hunt which is not very hilly. Everyone that has ridden it has had that smile when they came back.
