72v Razor MX650 Welded Freewheel Test Ride

[@BubCityHoodRides]

Still pretty quiet. Thought you were running belt drive

[@Rippinandfishin]

great video

[@RokeroLoko]

Pretty clean build nbs, clean tail light, got a link to purchase?

[@alexbekkala1718]

Heatsink will help cool your motor more than drilling the holes. Having both done should be good. Have you seen actual running temps of motor?

[@RemcosFPV]

Yea I added the new heatsink and it keeps the motor alot cooler havnt tested in peak of summer but Temps are way down

[@Sanesaint1]

Nice bike best razor i have seen.

[@Sanesaint1]

I'm surprised no cops go down there

[@PatOutdoors]

Loving the look!

[@RemcosFPV]

Thank you!

[@Sanesaint1]

I have one the only problem is the seat is way too hard so I got a seat gel cover, for regular bike seat took my seat off wrapped it around taped it underneath and put my seat back on and now I'm comfortable

[@TattedTommysTv]

Those smaller holes in the engine caps are to keep water out I was going to open mine up but learned it's not a good idea have you had any issues

[@EmxBrandon]

Damn that things so clean and quiet, im assuming the electro&co 5kw kit? Makes me really want an mx the torque looks fun. Definitely convinced me to weld the freewheel on my rsf 😁🤘

[@RemcosFPV]

Thanks man it is the e&c kit. It deff has more in it but I was taking it easy in the vid.. been watching your build vid on your bike. Might have to pull the trigger on one soon haha

[@EmxBrandon]

@@RemcosFPV for sure i could tell you were going easy. haha front pops up like its nothing 😁🤘 and right on bro thanks for watchin ill be checkin out your vids from now on too 🤙 the qs swap is amazing man i still think the encoders have a little ways to get before perfection but mines feeling pretty dialed right now, worth it for sure. Its not even turned up all that much and its a monster 😂

[@maukaman]

You mentioned something about high humidity areas and motor heat.. can you expand on that a bit please? Thanks

[@frankfuter2347]

I think it has something to do with the battery lithium ion works best in heat but when it’s to much heat it can cause problems etc

[@Smokey00]

I used a box buzz free wheel it's insanely good instead of the stock one having like 20 something clicks this one has like 100 or something. Super fast engagement

[@RemcosFPV]

I've never heard of it I'm deff going to check that out. I have tried out the white industry freewheel but it still have that catch up to engage feel so for now I'm happy with the welded freewheel

[@Smokey00]

@@RemcosFPV I think the stock free wheel has like 20 points of engagement and the box buzz one had like over 100

[@Smokey00]

@@RemcosFPV how long have you been running welded Free wheel does it affect the motor going the other direction?

[@RemcosFPV]

@@Smokey00 I've been running it for 3 or 4 months riding it almost daily. It does not affect the motor from going the other way. How is that possible?

[@Smokey00]

@@RemcosFPV lol iono I guess the only downside is you can't coast as long

[@JonnyDuzzit]

I just built my sx500 and was hella on the fence about welding the freewheel, this video made my decision Edit: btw, whats your motor and controller setup?

[@RemcosFPV]

Sweet glad it could help. I'm running the electro&co 72v kit. 6000w motor. Was taking it super easy in this video

[@laynag3852]

I have 3 of these welded the freewheel on 2! Didn’t turn out well for me!! Chain popped and locked up the tire, that shit through me and my 2 yr old about 15 feet!! I was using the stock motor, idk if a upgraded motor will make a difference.. is the upgraded motor capable of free spinning itself as fast as the wheel

[@RemcosFPV]

Yes the upgraded motor is brushless which spins more freely and has alot more power to keep it spinning. I think for stock applications the freewheel will work just fine. I'm pushing decent power so I did not like the way the freewheel had to catch up when im doing 30mph

[@bikelifegee]

What's the link for the mic sounds good

[@Armor220]

Would you happen to know which wire on the 3 speed throttle is for the LOW speed setting? I’m building this same bike for my teenage son and want him to be on LOW only for a while. Thanks in advance!

[@RemcosFPV]

Mode 1 (low) is going to be the blue wire coming from the 3speed switch. Not all throttles are the same best to look at the wiring diagram for whatever throttle you have.

[@mikegeorge2767]

How much did it all cost you besides the Razor bike.?

[@bmhs1928]

How did you mount the front rsf wheel, my brake caliper doesn’t clear when I mounted it

[@TURBOMOOSE]

I might have missed it in the video but what motor are you running?

[@RemcosFPV]

The 5000w electro & co

[@Turbski1]

Whats the range on these things

[@RemcosFPV]

My batt can get 35-40 miles range full throttle

Link to speedometer? I would like that on my build.

How did you attach the front brake?

[@Moscowmuleproductions]

What handle bars are those? really nice looking bike.

[@RemcosFPV]

Thank you. They are just some pro tapers . And I had a renthal pad laying around and I used that to match the color on my bike I didn't like the yellow from the pro tapers

[@MitchyToro]

@@RemcosFPV Are your bars cut? And are those the stock 7/18 bar clamps on the bike?

[@RemcosFPV]

@MitchyToro no bars are not cut I like and yes 7/8 bars. You can see more pics on my ig. @remcos.builds

[@maukaman]

Has anyone tested regen braking with a welded freewheel on a razor? I ride up and down some of the steepest hills in the country so it’d be awesome to get a little charge back on the downhills while saving the brakes a bit!

[@RemcosFPV]

Yes it works, i currently have it on my setup now. If your running a kelly kvd all you need to do is change the parameter for tps regen current I run it at 5-6%

[@maukaman]

@@RemcosFPV nice! Good to know. Eventually I’ll probably be upgrading to a Kelly Controller but for now I’m rockin a cheap ass china 3,000w. Most of these cheap controllers aren’t setup for regen stock but many of them are capable of it. There are pins on the board to solder wires to for connecting regen switch. I imagine It won’t have the precise control required to make regen work correctly on a chain drive setup like this though. Thanks for the info!
