Ive been looking at the all terrain ultra HT for a few months now. Let us know how you like it. Also how was dealing with M2S?

I had my eye on (waiting list) https://www.radpowerbikes.com/products/radrover-electric-fat-bike for a few months but it has been back ordered for a while now and they cannot tell me when it is going to be available.

I did not have any problem other than it took them a while to generate the order (about a week due to COVID) and another week for the shipment. They only have one shipment option, by freight (Old Dominion) for $285 IIRC.

So far just rode it around the block and it can go fast and not bad pedaling without assist. This is a massive bike (80 lbs). I ordered a medium frame (L and XL are available) and it still dwarfs me. Hopefully, I get to ride it out at the bike trail this weekend. Will pass on any information when I can ...
 
I was looking at those hard till I found out we can't ride them any different places than a motor cycle or 4 wheeler, that was a buzz kill!!
Yeah, but these are near silent...

I have a Luna X1 Enduro. It's the bomb.

Something to be aware of, the quoted and/or extrapolated ranges are misleading. A nominal 48V battery will range from ~54V at full charge to ~44V at full discharge. To get 750W nominal, at 48V nominal, you're pulling about 20A (after resistance, V sag, etc). As V drops, current needs to go up to keep the wattage, and the motor/battery will hit a limiter.

On my bike (Bafang 750W mid-drive, 14Ah battery), my output goes from ~950W at full charge, down to ~750W at 50% charge. Then it really falls off the table. By the time I'm down to ~30% charge, I only have 250W and falling. When you're used to >750W, 250W feels like you're towing a horse trailer...

That said, my fat, old, out of shape butt can still get a pretty reliable 18 mile range before the power drops off so much you really start feeling the loss.

The thing that's really cool, is you can tractor up some STEEP stuff. I did an experiment, along with some calculations, and I figure you can easily go up a 20% grade, @ 6-7 mph, for 6-8 miles while fully loaded with hunting gear, with about the same exertion as a leisurely hike. Since it's downhill on the way back, you don't have to worry so much about saving much battery.

Also. They are just fun. Mine is now my main commuter vehicle, and I put in about 100 miles per month. I get a little bit of exercise, save some CO2 emissions, money, and vehicle wear and tear, and get to enjoy the fresh air.

Anyway, congrats on the purchase. I bet you'll love it.
 
The specs on the website say the bike is 62 lbs. Maybe that's without the battery? I'd be curious to know, as it has implications for the bike rack you can use. If you've found a swing-out style rack that handles the load and you're happy with, I'd be interested to know. Thanks

I have CURT 18085 Secure Locking Tray-Style Trailer Hitch Bike Rack Mount, 2 Bikes, Fits 1-1/4, 2-Inch Receiver (https://www.amazon.com/gp/product/B072K3J9SZ/?tag=lrhmag19-20) to haul my wife's bike. It is supposed to hold up 90 pounds.


Instead of buying a new rack, I am trying a CURT 18091 Tray-Style Bike Rack Cradles for Fat Tires Up to 4-7/8 Inches Wide, 2-Pack (https://www.amazon.com/gp/product/B01M1SG5RQ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) first.

We shall see ...

Yep, I read the same thing. Hopefully, "if" that happens, it is all downhill. 😇 I am also considering an additional battery but very pricey. Thanks!
 
I've been looking at the E-bikes for quite some time now as a means to keep me hunting into the 70's (age that is) but what is hard to find is their weight capacity and effect on power consumption. Since I am a svelte 6'4" 255 lbs or basically Shrek size, the bike's capacity is big deal and major decision maker. The other problem for us normal size Shrek's is frame size but this one looks pretty good from that perspective. Anybody in same boat and have some info?
