SURRON ULTRA BEE "REAL" RANGE TEST

We put our upgraded Charged Cycle Works 72v 76Ah Battery in a Surron Ultra Bee and sent it on a massive trail ride trying to keep up with Dirt Bikes.
We think it did incredible! What do you think??

This is a range test for an aftermarket battery...... Misleading title.

[@ChargedCycleWorks]

A few clarifications, since we filmed this video the battery featured has updated specs to 72v76ah, slightly higher than we mention in the video. Eco mode was never used due to terrain/speed, D was used in normal terrain and Sport for all the steep hill climbs. Regen was set to 2 for off-throttle and 4 for brake. However downhill was mostly not using regen because Nathan was keeping up with the gas bikes and using regen on the decent was too slow. You could gain some additional range by consciously using regen more aggressively. The PSI we typically run on these bikes with 18/21 tires is 10-12 with tubes, occasionally as low as 8 if there are no rocks to bite us. The mousse tubes we ran at Redbull TKO were the Plushie in the rear equivalent to 6psi and Platinum up front 10psi. 50t Sprocket with 18/21 wheels and Dunlop MX53 tires. See description for links to the products. Thanks!

[@DukeFerg]

Thanks for the break down here, really appreciate it. Could you guys give me guidance on the 50t/53t sprocket choice? - Is the 50t much worse for hill climbs, power wheelies, and speed compared to a 53t?

[@Tazdeviloo7]

Only a 72V battery? The 82V battery should go even further then, about 10% more kWh. Amazing

[@MrChadx1]

@ChargedCycleWorks You didn't mention it in the video, but after the 49.62 miles, what was the battery SOC? Did it have a nice 10%+ buffer? or was it at 0%, 2%, etc.? We do a lot of 45 to 50 miles rides and don't want to end up below 10% regularly (plus, that range will decrease a bit with battery age/usage) so trying to understand what state of charge was left after the 50 mile ride. I think that's an important bit of info. Thanks! [Edit: Disregard. I found your answer to that question further below. So unfortunately, still not quite enough because running battery to nothing isn't something I want to do every ride. Thanks for the info. You posted.... "It was pretty much dead at the end the bike was still moving at reduced throttle but it was about 3% and we wanted to get the bike to a main road to pick it up with a truck rather than be stuck in the backcountry, once we were under 10% we hit the eject button to the closest road. We were only 4.5 miles away from the trailhead, SO CLOSE!"]

[@Mountainslayerz]

That was a great ride. So impressive to see that bike keep up all day long with our gas bikes.

[@DezertSlayer]

Such a fun ride.. thanks for having me!

[@trail.squatch]

What’s more impressive is the elevation gain!! So in other words, if you’re riding lowland trails with less elevation gain you’ll get even more range. This is killer. Great test. Thank you guys. You rock. Can you tell us your regen settings??

[@ChargedCycleWorks]

We run the off-throttle setting pretty light, usually at 2. Then on the brake setting we run it towards the max which lets you control it with the brake lever better. We find when we run off-throttle at high settings it's too jerky of an experience and annoying.

[@JeffKendallWeed]

Great video! Im interested in the Ultra, but when C class racers can’t even complete a 2 hr harescramble, it doesn’t quite seem feasible for an A class rider to do more than an hour or so- but looks like the aftermarket battery can help that substantially. Thanks for posting this!

[@ChargedCycleWorks]

Stay tuned for an upcoming video, we've been racing the Ultra Bee in Grand Prix (50-60 minute) races that are part MX and part desert, brutal conditions for an electric bike to finish. In the 3rd round we also took a Stark Varg with us...hope to publish this video soon.

[@igoyippy4skippy]

Great video... I got the 80V 76ah battery and the EMBX controller from you guys. Excited to get it installed and see how much farther I can go on my Ultra Bee.

[@brandonsmith5141]

How much farther have you been able to go?

[@douglasyoung3992]

Great info on the Bee, watching you guys get to ride wherever you are makes me sad I'm in northwest Ohio.

[@sarahenry3879]

Such a fun video! Makes me want to go load up my Ultra Bee and go riding! Thanks for the video. What size sprocket was he running?

[@ChargedCycleWorks]

50t. Same here, not enjoying the thought of winter creeping in on us right now. :(

[@mconradb]

​@@ChargedCycleWorksWinter sucks, but it hasn't stopped me from riding!

[@JUSTINHAWKSMITH]

Awesome video I want to ride a ultra bee someday. Looks like a super fun bike. I have a LBX I built here on my KZbin channel , got the wheels from you guys along with a few other parts. Keep up the great content !

[@taylorpriest1061]

Great video guys! looks like a good time.

[@NCtrailX]

Great video with absolutely awesome scenery and trails! Have a Light Bee X and am seriously considering upgrading if I could sell mine.

[@northshorelongbow]

Fantastic ! ....when you guys coming out with an upgraded battery for the Storm bee ? .......a 120V 100ah would be absolutely wicked.

[@Hunter_Heart]

We definitely need bigger battery. One that can match or exceed the tank of the gas bikes without babysitting/not racing, etc. I don’t mind the battery bulge out or cut up the sides of the frame for the battery expansion.

[@northshorelongbow]

@@Hunter_Heart Batteries don't really need to be bigger, tech is moving fast they should be able to get us more powerful batteries with way more capacity in the same package soon.

[@Hunter_Heart]

@@northshorelongbow If you know about solid state battery. EV industry and battery storage is going to eat them up, before you seeing it in personal mobility. Atleast 5 years from now.

[@therealbojak]

the Nate montage was so funny. hahaha.

[@Adventuredriven]

great video, where were you guys riding at ?

[@Varkreker]

Awesome! What tires are you running, please?

[@ChargedCycleWorks]

We run 18/21 on the UltraBee and it varies based on the terrain, be sure to never go larger than a 100 on the rear, the weight gain is a range/power killer. We are very careful with tire weights, in fact on our website in the footer you can find a tire weight database for every tire. On trails like this we would recommend our Enduro wheelset which features a lighter weight VE33 in the rear, but on this day we had MX53. chargedcycleworks.com/products/18-21-wheel-and-tire-combo-for-ultra-bee?variant=43874992128216

[@DukeFerg]

what tubes were being used? - Assuming a beefy one?

[@ChargedCycleWorks]

These bikes are much lighter than gas bikes so we simply run your average 2mm tube: chargedcycleworks.com/products/tusk-heavy-duty-2mm-tube-for-sur-ron-or-segway-x-260

[@starmania909]

just waiting for that half weight 2x 100 mile battery soon

[@Tumid1]

While impressive how many of you weigh 150lbs.??? If battery range to body weight on an Ultra Bee is anything like ebikes....a "normal" sized 180+ lb. American on an ebike will get 20% fewer miles than a 150lb. rider.

[@ChargedCycleWorks]

weight has an effect but not 20%, you're comparing a 50lb ebike to a 200lb motorcycle. ebike is affected a lot more than the motorcycles. Our crew weighs anywhere from 140-200 lbs and with all the riding we've done the range is mostly affected by how aggressively you twist the throttle and your overall speed. Our 200lb rider often has the same or more range simply because he is less aggressive with the throttle.

[@gsu1972crew]

I'm 235 naked so I'm not getting that range on that exact ride. On average, regardless of rider, assuming the exact same course and pace, what % range increase can you expect with the 7276 vs OEM? @@ChargedCycleWorks

[@joshc3926]

I'm 220 lbs before gear and I'm set up with 18/21s, 54T, roller chain and stock battery. I get about 20 miles of legit mt range single track in D mode before I have 20% remaining (so ~25 mi if I drain it dead). Pretty bad! Gonna need CCW @ChargedCycleWorks to have a sale on those 76Ah batteries if I'm gonna have any chance of doing 30+ mi rides light these lighter riders.

Is this compatible with the torp 1000 controller?

[@ChargedCycleWorks]

we are testing a Torp1000 right now, hope to produce a video about it soon. At the moment we are using it with the same battery featured in this video and providing feedback to Torp about our testing.

This or Stark Varg?

[@MB3Drift]

I almost bought an Ultra Bee, looks like a fun toy. Still sounds kinda lame. Don’t get me wrong, I will be thrilled to be able to ride an electric full size (or « half size ») enduro bike, but having so little range, even if its not harsh terrain (and by the video it wasn’t) but a lot of climbing, seems pretty much a waste of money, at least for now. For the price of the Ultra Bee, you can buy a nice used enduro bike, pilot gear, gas, insurance and maintenance for at least a couple years, without having range anxiety and riding a little trial/trail bike. And I don’t count the 3k dollars for the bigger battery to have 10 more miles of range! KTM was supposed to release a new E-XC in 2023, with 5,5kWh of battery, and nowhere to be seen yet. I’m still wainting for it, to be able to rip the trails and go everywhere (40 miles from home) without anybody noticing 😂

[@ChargedCycleWorks]

The electric experience is one that's truly fun and incredible on the trails. If your prime trail mileage is around 25 miles then the ultra bee is a killer option. Anything beyond that is definitely gas bike range until battery technology gets further along. But I can promise you if you get one you'd love riding it!
