@tjcutler90hell yeah you’ll have a blast bro I’ve already banged myself up on it a lot of power for the size.
I put a surron throttle and sicky mx grips on mine and a dnm 1200lb shock w/piggyback reservoir and it rides sooo much better. doesn't bottom out AT ALL. I strongly recommend it best 200 dollars u could put into it
Thanks, I used your link & got an f18 it goes faster each time I ride it more of a "me" thing ;) ordered a new throttle, so its coming Im thinking about a larger rear sprocket - sure that will slow the top speed, but climb easier (there be many trails around belly acres) so far Im liking mode 1 as in mode 2 I had to lay on the bike to keep the front wheel down while climbing. ;) Im hoping the new throttle will help control that. the silly bike likes to hit 17 & 19 oops, I was just half throttle (?) it is a bit radical as it is, just not the best control. in mode 1 [with me] it climbs just fine, smoother 12% 22% 27% up n over, less theatrics. ;) it has been a fun surprise, with each ride Im learning to be more confident in me and the bike. it is much different than my ebikes more different than dirt bikes. being mini/midi size is something this guy needs to get used to. that reverse? I thought it was just a gimmic, but it is useful & how it works is very nice.
got my f18 a few days ago its a fun thing just ordered the throttle Im kinda thinking to get a rear shock And look at front fork options. it is a bit short at a 45" wheel base maybe get a 19" front tire too (?) Im thinking a little extra low end to go slower & putt up those steep grades :) the tires being nylon seem tough, but my thought is to get rubber as that grips , wont last as long, but I ride where it belongs - in the loose dirt/gravel yeah, Im soft, the seat needs extra padding. I had a trials bike yeas ago, that was a thin seat, but I seldom sat down being a young trials type rider. Im older now and just want a comfy trail ride. :)
It’s the riders not the bikes you can’t expect jumping hill after hill and bump after bump on a 1200$ dollar bike it’s well worth it just don’t become a stunt man and your bike will last years common sense
This one said E-007 the cleared to fresh start and wicked fast mm. Lots of chain noise and really narrow narro. Spot on review
Found it! Turn the bike off, hold down the front/rear brake and twist the throttle completely wide open at the same time, then turn the power button on. Keep holding the brake and throttle for about 15 to 20 seconds until an "air O2" or similar code/display resets to zeros, then release them. --- HS.. 6'6" 250 lb up slight hill @37 mph!
Just assembly and test rode settings 1= 10mph, 2=15mph and 3=20mph... not the 17, 28 & 46 as advertised. Any way to change this? It is amazing torque-y.
@RCSky7711thanks for the info but it didnt work, i changed the “Current Calib” from 50ms to 10 and almost flipped dover 😅 But i cant seem to go faster top speed lol, alot of the settings wont change
@3CMiniWorksas soon as the light turned green on the power supply I unplugged it and it turned right on. Hallelujah! I just went 30 in mode 2 to test it. I'll be going on some gnarly trails soon to see how it performs. Happy riding!
@VoltedAdventuresas soon as the light turned green on the power supply it came on. It simply wouldn't turn on before that. Then, I had to adjust the chain because it was crazy tight. I just went 30 in mode 2. So, it looks to be working now. I wonder if other people had that quirk? Anyway, thanks for your reply. I'll be taking mine on some gnarly dirt trails soon. Happy riding!
@AxzytezSo, after full charge it turned on but didn't move. So, I loosened the chain and now works great! The chain was obnoxiously tight
@3CMiniWorksI did not. I actually unplugged it, then tried. That is when it flashed on for a split second and died again. That gives me some hope it is just completely dead on arrival. I'll try to forget about it and try tomorrow. I'll come back and let you know if it turns on. Fingers crossed 🤞
Did you try it while charging by chance? Mine did the same thing when i tried to turn it on while charging. And it didn't repeat when off the charger.
@Axzytezafter charging it for 45 minutes I turned it on and the screen turned on for a split second then died. I think it is just completely dead. I'm going to let it charge over night then I will report back. After it came on for a second I'm feeling optimistic...
@3CMiniWorksI tried that and the dash came on for a split second then shut off. I think its super dead....
Downhill I hit 58mph on my ver. 1.0. and it will do 55 flat (165lb rider)
@3CMiniWorksyep. But chain noise is too much. I also have one of these, don’t know how to reduce it.
I keep getting a error 22 straight out the box 😢
mine's working fine? I Haven't had a problem with it!
@BrycenDones My Accel time was set on 30 seconds. It is supposed to be set on 5 seconds from the factory, (which is still way to long). I have it set on 1.2 seconds now its a little sketchy I get some whiskey throttle doing wheelies, I may change it to 1.5 seconds but even in mode 1 if you whack the throttle the front end jumps off the ground
Yes I’m 6.2 250 plus it pulls so amazing I only went like 45
If anyone is doubting this I just got mine an I’m 6ft 210 and this thing is fast tons of torque love it!
Mine kept bottoming out also I think it was the kickstand I might have to remove it
I just got one the other day this bike is fast an dangerous
I’ve been on both and I prefer the g300. Seems to be a more solid frame and just a bit better quality
I weigh a little more than you and this thing rips with me on it lol . Such a fun bike!
i got a happyrun. it does 60 lol people was sleeping on it
Wow, you've definitely put a lot of work into yours! Thanks for sharing your experience. Mine didn't have those issues, but it's always helpful for other viewers to hear different experiences. It sounds like you've got it dialed in now after all those upgrades and adjustments. Ride safe and enjoy the trails! 🏍️🙌
Also run the tire presure lower that what the factory says 31 psi I ride it at 28 psi little better control.had to ad the rea fender spacers to raose it to protect the rear shockfrom mud and dort.and still will need to put fender extender on rear at top .
Also I moved the handle bars forward for better positions .the loud is the chian hitting the chain guide braket .once fixed its very quite but still its a magnet motor .
I buaght it and have had to repair almost everything .poor assembly of the parts damaged parts from factory mess ups front sprocket spacer was squashed by over tightened and the swing arm washer was damage from miss alignment during assembly from factory .no grease any where I've had to disassemble and grease everything also the rwar shock was not installed correctly I had to put washers on each side on bottom and top bolts to keep shock from just flaming around , I threw away the stupi front plate also got in the way of the wires and brake lines. Also had to raise the fork clamps raise up the bike on the forks ,als removed the oil and installed my own and made spacer for front fork springs .and had to adjust the rwar shock tighter for my wght at 150 pounds .went on app and adjusted the tpurqe limiter and also the throttle high and throttle low .and thats all the mods so far also I did have troubles with the chain guid the bracket hit the chain so had to bend that also
I’m 170, and ride it really rough. Mine kept making that noise. It was the license plate holder. I’m not riding on the road so I just took it off and it hasn’t made any kind of noise on a big bump yet.
@BrycenDones lol yeah the speed is already insane!! but id say be careful on the suspension because you saw how weird the front forks were for me!
I just got one Friday, the power is awesome
no but dude.... if go crazy on the throttle before the jump, you'll catch plenty of air, this thing is crazy!!
That was the first thing I did. That kickstand is just way too low
I brought tools every other time I’ve been on it now! 😂
I’m hoping I can just put it together a bit better than they did from the warehouse and it’ll work better. Either way it’s a definitely a kids bike. I was really rough on it though!
Don't go with happy run seriously. I ad so many motor issues grinding noises overheating broken parts. finally returned the bike after a week and they charged me $200....
happy run worstttttt bikes no joke. I had tons of motor issues grinding noises and broken parts. customer service is crazyyyy. the try to nickel and dime for everything. I finally returned the bike and they charged me $200... sh*t show
It is fast for $1400 wow, whats your problem.
You have to tune it I got mine unlocked from 20 max speed to 45mph…
I received two and both are locked at 20mph.... P08 does nothing and it's a holiday weekend so looks like a loss
I think its a great deal for what your getting. U want that torque
Sorry this thing is ugly as hell and the geometry is crazy. Frame looks cheap too.
F18 is 245 Nm vs around 250 Nm for the surron light bee. Trust me with how light this thing is. It feels faster if not just as fast. 5nm of torque isn’t gonna make any difference in the real world.
Been awhile since I rode the g300 but I’d say. G300 a bit more better quality but this thing is much faster outta box.
Looks familiar to some e motos. But the parts and (controller) might be a lil different.
Similar set up with the battery but much taller, different wheels. Feels faster as well
Thank you so much!! 😄⚡🏍 It’s definitely a blast to ride — the speed and acceleration are wild! Hope you get to try one someday!! 🙌
