Just curious if any one has one and what their thoughts are.
I am thinking of this bike radrover-electric-fat-bike would be good for my wife.
Then I would have a hard time keeping up with her instead of the other way around.
Also if we are at the dunes she could take it out on the beach and explore while I am out playing on the TW - the videos are quite impressive on how well it does in the loose sand.
Fast forward to where he actually takes it for a spin about 17 minutes in.

Did not review all the video
Questions that come to mind:
Warranty support
Cost and availability of replacement battery
Tires/tubes easy to find
Maximum grade it will climb without pedal support

I was going to buy or build two bafun mid-drive fat tire bikes before we decided to get the Tw's. My daughter who lives on Catalina Island, before she had full interior access, bought a chinese carbon 49er prototype MTB with a 750w bafun mid-drive motor because she could drive to the middle ranch with out special permits. That bike was @$2200. But retails for @$3800. Her bike does over 27 mph which is damm fast. If you have never riden any electric bike you will be blown away by how much fun they are. One advantage to a mid-drive is they will climb better, but that is a new type of hub motor with gearing that should climb great. They have hit All The right stuff with this bike. I think for what it is that is a great price. Your wife will have a blast on a bike like this. He even mentioned you could put a supension seat post on it for more comfort. Spare batteries are @ $400-500 ??? last I knew but may come down soon. Any bike shop can fix all the bike parts. The range is great. The bafun electric parts are very common in a lot of e bike shops now and online. What I like about this set up is the 750w motor. There are some laws restricting speed and power on the street. So most ebikes have 5oo watts or less. With this set up you can fool the controller by changing wheel size and top speed will increase. Also you could drive it with a 52v battery which helps keep the motor cool and add more power. Plus there are programing tricks you can do to the controller. Of course I am not recomending that you break the law while riding this bike on the street.

If the electric bike is actually used a lot, then go for it, especially if the rider has health issues and can't pedal a real bike.

I had an electric bike for almost two years, I thought I would use it to commute to work once in a while. Turns out I'm too lazy to go through the logistics of spare clothing, timing, and lunch making. I think I put about 40-50 miles total on it during that time.

I sold it last Summer at a significant loss. I simply did not use it as I thought I would.

Warranty support - 1 year
Cost and availability of replacement battery - $499 and they are available
Tires/tubes easy to find - yes
Maximum grade it will climb without pedal support - 15%

This bike cost less than my last mountain bike and my wife is not all that adventuresome.
i ride to work almost every day rain or shine on my Kona Dew Delux and can maintain 20 mph on the flats. On my Norco Shinobi 29er, I can easily maintain 18 mph and I know my wife does not like to go above 15 mph on a bike.
This would allow her to keep up with me when we do go for a bike ride.
I had originally bought the TW for my daughter, but it soon became my fun toy and this may also end up as a new toy for me.:rolleyes:

For your wife, or anyone that wants to mt bike, but really will not be strong enough to really go up and downhills, it's a good alternative bike.
The price is low enough to get in the door. If the electrics go out you still have a viable fat tire mt bike. And you could switch out the rear hub and lose the battery and have a fun ride.

I think for your wife to get out and ride with you it would serve purpose very well.

I demo'd an ebike, I don't remember the company name but it was really a full suspension downhill mt bike design built with XT components and a motor/battery that could go over 20 mph.
It really couldn't climb the dirt trails we had been doing but it did make it much easier for me especially since I was tired. I was impressed but it was like $5k.

When I can't climb the trails I like to mt bike on I'll look into an ebike more seriously.

I take it she doesn't read this forum. Lol. Check out youtube for videos of fat tire bikes in the snow they are pretty good in snow too. A couple of years ago it was going to cost me at Least $1100 or more just for the mid-drive parts with the wide bottom bracket to install on a fat bike not counting the bike. It was hard to find the brake - motor cut out levers and the most of the fat tire bikes didn't have suspension front forks. The batteries are probably good for 1000 charge / discharge cycles. That's 20k+ miles at 20 miles per charge conservatively. 40k with pedal assist. It doesn't hurt for the batteries to sit especially with out a full charge. In fact if you weren't going to ride it for a while if you leave it charged at 50-60% and then charge it before you're going to ride its better for the batteries. These batteries loose some capacity with age but they are lasting well over 7 years.

what are the charging options? is there a set up for solar? the battery won't last too long when dry camping.
Most charges are 120v so you would need a generator or enough panels and battery storage to run an inverter. It's a 48v 11.6 amp Battery so with a high capacity charger ( 4 amps or higher maybe) you could recharge in a couple of hrs +. It comes with a 2 amp charger so 4-6 hrs with the stock charger.

EDIT: Sorry I jumped to a wrong conclusion about this ebike. It would still be a great bike for your wife to ride. A 750 watt hub motor is pretty powerful, but when you stated it could only climb a 15% grade that was a red flag for me. When I saw the gears on the back I assumed the motor used them it doesn't. I took a better look at the bike and realized it's not a special multi geared hub motor. A regular hub motor is direct drive and it is variable speed but one gear. This is what the red rover is. If you want a badass offroad fat tire bike a mid-drive motor is a better option. A mid-drive motor fits in the bottom bracket and drives the front sprocket which then drives the rear gear cluster. So you now have a geared variable speed motor driving a 6-7 speed transmission. You can put it in a low gear and now climb almost any hill. Or on the flat you can put it in a higher gear to go fast. When I last looked it was $750-$1000 for a Bafun HD mid-drive kit, $500 for a 52v battery and charger and @ $500-700+ for a fat tire bike. The hardest part of installing the kit was getting the old bottom bracket off. The rest is pretty much plug and play. These bike have 25amp controller on them with some sites doing custom programing for more performance. There are display options to look at. Go with a 52v battery less heat on the motor and more power for less amps. Do some research and check it out. My daughter test drove many ebikes most had hub motors and they couldn't climb a steep hill that ascends from Avon up to the interior. Her mid -drive easily goes up it. Most stock mid-drive and hub motors are less than 500 watts due to street speed and power restrictions. That's why a kit like this is kinda attractive.
