I have the Grizzly and the trick to avoid front wheel spin is to start from a stand still on the rear motor only. Once you’re rolling, switch to both motors. It carries me up steep hills at 30 mph and I weigh 265 lbs.
Offroad climbing is best suited for a low geared setup, so motors can turn freely, without amping up and overheating. Geared hubmotors will NOT last long riding in this style you demonstrated. Gears subject to strip, and motor winding damage imminent…I love low pressure fatbike tires for the traction they provide, and the smoother ride! I live in the hills, remote, so I built a 26” fatbike frame, with a low standover, harley seat, and a gearless 1000 watt hubmotor with double gear reduction(jackshaft). 8 mile an hour, flat out….but I can pull and climb all day long without any heat…and direct drive means I can utilize regen for braking. I’ve been using it to skid 12 ft green logs out of the bush…no problem😀
I have a AWD Wallke and I was annoyed that the front motor doesn’t kick in 100% power until a few seconds. However, after watching this, I know why! Great video!
Shifting the rider's weight forward will also reduce front wheel spin. There is also a setting in the controller to reduce "ramp up rate" of power applied to the wheels.
@@AdamSwords It varies by controller type, but they all have it. Some call it delay, or other names. They all do the same thing. They adjust it so that high power isn't instantly put to the motor.
I have an AR D-Class. It's the baby brother to the Grizzly. It's plenty fast and powerful with dual 750W motors for my first bike. Do wish it had a rear suspension and 52V battery.
The Grizzly is actually over 3500 watts peak (1850 each motor) I learned to ease into the throttle or the front tire wears out quick on the Grizzle. And the batteries only run one battery at a time. It will default to the rear if both are on. You probably drained the battery out on that climb because it should of carried you up even that incline. I'm very surprised bikes haven't begun going dual motor after the success of the Grizzly. Most high performance scooters are dual motor right now. Imagine the speed of ebikes with 3000 watt motors. I think the reason bikes like the Surron don't is the weight of a motor in the from would limit kids doing wheelees. And my Grizzly never gets old, I'd never ever downgrade to an X class. When I change the switch to ride one motor if i need to preserve power I never last long on it. The reason you have 2 batteries is to make sure you don't run out of power. The extra weight can be illuminated by just carrying one battery by removing one.
That looked like a lot of fun! I was worried that with the added power from the dual motors that you could easily lose control and zip over the edge of the hills. Thankfully, you are an expert rider. I could see myself having a blast on an e-bike if I was 30-40 years younger, and several pounds lighter. Adam, thank you for another exciting video 👍 Thank you to Jordan as well.
Great footage and cool bikes. Usually there's a setting for soft-start so you don't spin out the front wheel. I'm thinking of adding a front motor to compliment my 1kw rear. Thinking fully independent systems is best.
Fun stuff. I just ordered a dual motor Fabulous EMX Extreme. I don't think I would like those stationary seats, and being above 750W takes it above the legally recognized ebike category in most states. Furthermore, I would guess it is the additional wattage causing it to overheat. Here in Alaska people not only use them for commuting but hunting and fishing.
I feel like Grin Technologies would have something that would temporarily delay or weaken the front motor, to prevent that annoying burnout. Like an adjustable ramp up for the front compared to the rear or something. Not only is that destroying the front tire. But that may also make you fall accelerating out of a tight corner. If I was to build a dual motor ebike, the front would be like 500watts, and the rear 1000, or, I'd use a Cycle Analyst from Grin to limit the Amps of the front motor, because of the linear relationship between torque & amps. Less Amps, less torque, same voltage top speed, and maybe a throttle signal bypass, to go around the CA, a direct throttle signal to act like a boost button.
Yeah adjusting the power curve for the front would be great. Essentially keep it at 25% power up to 5mph, then slowly ramp up the percentage after that until say 20mph.
Here is the Truth. Listen up young Padawan. I know ALMOST everything about Vehicle Design and am now planning to build a 2WD 'Bicycle' for myself, and your Video has refined its Design a little further. It is EVIDENT that having too much power in a front motor is a BAD Idea if BOTH Motors are controlled from ONE 'Throttle' therefore a 1000W Rear and 750W Front is a wiser ratio. (Also with Tyre and Rim width sizes.) Further, independent Thumb Throttles are recommended for Rider Power Balance. Next, there is already FAR TO LITTLE WEIGHT on the Front of a Standard Rover Safety Bicycle Design that's front tyres always last FAR longer than the back. Identical wheels for different Steering and Drive Jobs makes no sense and are chosen for Economy of Production, NOT Engineering Efficiency. Are MOTOR CYCLE Wheels the same ?? Sit on a normal Bicycle, weigh F + R on bathroom scales. See the difference. At MINIMUM this should be calculated for Tyre Pressures. The Batteries in a Leccy Bike should be carried in FRONT of the Frame, one each side. I think that I will style mine in like Honda 50 Leg Sheila, +maybe ADAPT them !, one each side fixed to the frame, behind the steering head. This will not be the first amazing Bike that I have built. I have a VERY Nice Muddy Fox Full Sus just waiting for its opportununity. Forks like on a Fireblade ! Last thing, I am 72 soon. Never give up. 🚵💨💨 WHOOO Hoooo00OO !!! 🚓🚓🚓💨 .
For hunting here in Nevada I got an E-CELLS Super Monarch Crown e-mtb. 2 wheel drive, 2 batteries, dual suspension, 2.3 mm thick brake rotors, 9 torque sensor assist levels, ROK SHOX shocks, Shimano Deore gearing, Samsung batteries. AND all for $5,100. Compare that to the way overpriced RAMBO Megatron at over $7,000.!
That front tyre looks 1/4 gone after all that wheelspin. LoL. Great review. Great content. Laughed as many times as you did Adam. Lots of love from Australia. Abs.
I have an Onyx as well, main ride. My play bike is a Surron. I did try the dual motor Ariel and it performed poorly on trails. It felt so weird, the weight distribution was odd. You should do an off road, side by side with a Talaria or Sur, both 3k mid drives.
Lool you tortured that bike!! Companies that gives you stuff to review, must really believe in their products, cause you give them hell 😄 love from Malta 🇲🇹 ❤️
my seeker 26 has some kind of soft start.. on a gravel road and low speed and full throttle i can make the front wheel make a tiny burnout . but on normal road its not spinning up
I was using a 70mph awd scooter for a while now, thinking of switching to awd bikes... a gravel road with an awd personal electric vehicle like this, God it's amazing. We do wonder how well this would work up Mt Everest. I'd be doing 50mph until I hit a turn, then I'd go flying 😂😂
I remember flying my drone from a sail boat and forgot to put it on moving home location. It stopped flying as it was too far from the original home spot and the battery was going basically it was going to land in the sea. Luckily we got the boat back to the point just In time 😅 won't forget next time!
I’m willing to bet the bike would fly up that steep section with all wheel drive engaged. Also, early congrats, you’re about to smash through 100K subscribes 🎉
I have a Grizzly, I'll never buy a bike that's not awd again... Not just for the speed, I've been in snow and sand going slow and just couldn't go where I've gone with single drive
sweet, im buying a E/bike soon and wanted to see what trails are in O.C. where I could ride mountain bikes too. but for sure when I get my new E/bike. thanks man.
You should test both bikes with rear wheel on only.👍 Or you ride with rear wheel and turn on front if needed. Oh.. Toward the end of the video you figured that out. 😁👍 I have the Kepler which would be about the X class specs. The Kepler is probably much easier to pedal longer distances and has the 26" fat tires which may give it some better off road advantages. Larger wheels roll over things a bit better.
my friend just bought one and EVERYSINGLE time we ride it we are just giggling and laughing. i have a 48v 500w custom ebike chopper and it gave me the idea to maker a dual motor dual battery version of my bike. a dual 1000w motor chopper bobber ebike.
Catalina island was featured tonight on “UFO Witness” (the undersea alien base) . It was really good, lots of stories of an underwater UFO base around Catalina island. Have you ever seen anything??? I definitely wouldn’t be going out there at night after watching this!!! It was on Discovery HD here in the UK (Sept 16).
@@AdamSwords might be great if you did a video on it, maybe interviewing anyone that has had experiences around there, then maybe do a night trip with a few of your mates??? By the way I’m from London, am insanely envious of your life lol, my son is hoping to buy his first jet ski this Xmas , I’m hoping my son can come out there one day and live in the sunshine zipping about on the ocean and do what I never got to do… yet.
It’s a cool bike, but it’s basically a low powered motorcycle. At a certain point, get a license plate and insurance. I’m not enthusiastic about people going crazy and ghosting out on accidents.
Is using both batteries at the same time strictly for Speed? And I'm sure with one battery can get up to about 28 mph like most, personally I would use one battery at a time to get double the riding miles. The dual-battery seem like such a waste to use at the same time , but that's just my opinion, they are some awesome bikes
sweet I just love both bikes and your back ground was soooooo pretty, thz Adam your the best keep up the great videos and tell mikiepooh he is missed. love 2 the both of Y'ALL... ps us women r call gals.....lol 😆 oxox
I also have a dual motor ebike. The other day, i was going off road and my front wheel motor flew out the front fork. Does anybody have this issue with the dual motor ebike.
What’s the total weight it can handle, and height for tall old folks, I figure with a Camelback water bottle, and a catheter, kneepads, beanie hat with a GPS tracker we would be safe, huh what’s ya think? loads of fun watching you play you whippersnapper!
@Adam Swords you need to get producer Michael on 1 in a video just for the hell of it that would make for such a funny video 📹 😄 🤣 😆 😂 😀 I can't see his face now 🤣 😂
I've had the grizzly in my cart for a week now. I'm reluctant to hit buy because I'm 6foot3 and I'm worried this will kill my knees if I try to pedal on it. Any insight?
@Adam Swords I get that but you kinda do, especially when you have bored local police waiting to see if you actually put effort into pedaling or go full motor.
Adam, Yet another fantastic video. Just one quick question please. What happens if your battery go's dead? Is pedaling that monster much harder than a "Normal" bike? Live your best Life you only get one...
It's amazing bike man I have D class and now I bought the grizzly it's super fun bike very nimble you can throw around the corner ride the trails take you places quick obviously not for everyone it's kind a loud which I like and has lots of torque.
