I told you the Sabvoton would be a different beast, But, as I said, just play with the throttle curve and you'll be good. Don't go to far otherwise you'll cook that motor. Everyone was harping on about gearing, honestly though, That cog is already so small that lifting the front wheel with the right tune in it is what I would expect, the only thing I would worry about is the motor temp really and that would be it, barring the battery that is. Good on ya Andy, sticking to the end.
OMG!! You have done it again!!! What a fun bit of kit. 2 questions Andy How fast does it go now? How much did the total build cost you so far? Keep the the great content buddy!!!!
This is the sort of power I want from my bike, it's mental. I had a folding 250w bike but the frame broke so I've strapped it to my old full suspension 24 inch bike and it rips with 1kw and I've got some new parts coming to get it to 3.5kw peak but the motor is still 250w so it heats up quickly but with my tiny 4 mile range battery it doesn't get too hot
Andy, absolutely brilliant work. That thing is a little beast!! I held my breath when you were testing the temp of the motor. I think it will be absolutely fine in this winter but maybe attach a temp probe to it when it gets warmer
Fantastic Stuff! you might find a cheaper Chinese controller might be the sweet spot, smaller and less expensive as well, I think the motor will get very hot in the spring and summer though so I would put a temp sensor on it and use it as a cutout or warning device, you certainly dont want to run side panels, you could even used forced air to the motor via a fan, maybe from the top down if there isnt enough room, keep an eye on the motor shaft and sprocket, in my experience over the years I have seen these shred the key ways and pins fairly quickly when overpowering, also you might find the point inside the motor where they solder the phase wires to the motor windings will come unsoldered as the joint will run hot, worth remaking them, crimping and soldering them, you might also replace the hall sensors for something better quality, the cheap Chinese ones tend to fail with over temp, I always used Honeywell ones. I think it will be fine in winter whilst its freezing but it will roast in the summer, great job though mate, looks like so much fun, oh and the miserable people, I encounter them on my legal ebikes, they seem to think that they have ownership of cycle paths, I stopped saying anything to them, if you dont say anything they still mutter stuff at you, if they have to hold their dog by the collar as you pass they expect a thank you for that for some reason? on paths where the fucking dogs should be on a lead!
You're lucky to have access to all those different parts and stuff... If I had that stuff just sitting around, that would have been the first thing I did before riding the bike. LoL Awesome build.... I'm jealous of the Sabvaton and battery setup, very cool. 😁👍
Is it possible to fit a gyroscopic sensor in there somehow, so as the front wheel gets too high it restricts the motor stopping you from flipping off backwards. That way you can keep that throttle open pulling serious power wheelies!!
Awsome bro, looks like a success..Be safe and give us more on this..👍🏽That instant wheelie performance may need to be turned down some..Awesome as always!
Don't turn it down, change the sprocket and get higher top speed. Not sure if your motor is peak 10kw or constant, but if you're constant I only say it peaking in the mid 8k range so you can lose a bit of torque for speed.
@@GapRecordingsNamibia im inbetween the 2 worlds phaserunner is obviously cheaper and it being featured in the recent 2500w build his friend did got me intrested but this video cleared it up for me whats the benefits of either side
@@NaNFeArIngAmES Hi, yes the phaze runner is cheaper, the reason as I stated previously is because it is a medium power device mostly 4 to 6Kw max capable, the sabvotons are high power from the smallest which do 8Kw medium to 12Kw max up to the bigger sabvotons that are capable of 20+ Kw, then you have the kelly controllers that can hand out all the way up to 30Kw. On the other side of the extream you can get a nucular controller russian made that can dish out to 30Kw on bursts but they can do on board charging at up to 3Kw this is a charger controller combo.
That little thing is mental 72v and those amps on large wheeled ebike is wheelie prone .. with those little wheels the torque must be epic on that little ripper
Hi Andy please could you tell me what DIY ebike parts I would need to achieve 60+ mile range for an ebike build as I want range rather than speed. Hope you can help cheers loving the videos 👍
you just need a bike frame that can fit a large battery ( can be either shop bought or self made ) ... thats the hard part though because many frames are not suitable. I have turned a road bike ( tour de france sort of thing ) into an ebike before but it was not recommended because without suspension it feels very rough. To do 60 miles you need a battery capacity of around 1.5 to 2 KWH ( at 15 mph mode ), in other words the battery has to be able to output 2000 watts for an hour, worth of energy. 48v 30ah or 72v 20ah.
@@andykirby yeah! I got one of these(link below) on ali for $80 to put on a razor mx500 but it heats up pretty fast when I push about 100amps through it. I am thinking of putting a bunch of aluminum heat sinks on it like the hubsink guys. www.amazon.com/dp/B0855LXRSF/ref=cm_sw_r_cp_api_glt_fabc_HRTYB57F9EKXR6D3WSJ7
The heat sinks will defo help. I think this motor will be getting way hotter in the summer as it was a very cold day on that test run! I could do with finding out where to get replacements for these motors then it could be modded to maybe handle the heat better😀
Looks like you want about 80amps max at launch in your curve, anything over that should come in once you get over a low speed threshold say 30km/h? This things a monster, no surprise there though, those motors are rated for a fair chunk of power. Keen to see what you do for a battery for this one. Keep ripping it up man!
How do you think this would would this perform with the Sabvoton controller and the original 48v battery ? did you sort out a way around the charging ? and in your first video you say you had problems with putting the bike together was this to do with wheel/ brakes ?
Hello mate, we’ve got an XTM MX-PRO, 1300w 48v from xtreme toys (14” & 12” wheels). What do I need to make it perform like yours? Mechanic to trade, deff not an electrician but no issues splicing wires etc. I assumed I’d need a bigger motor & battery, but any suggestions would be much appreciated! Great videos BTW! Thanks, Mike
@@lifehackervideos5442 thanks for the info I am going to upgrade the moatar because my bike is bigger im definitely going to make my my own battery what cells would you recommend I use thanks.
So would it be possible to use this set up on a bigger bike with a possibility of getting it registered as a motorbike. Could save a fortune on build costs. Keep up the great work. Brad
I've got a question maybe you could help? I have a 1000 watt front wheel drive motor with a 13.5ah battery at 48v. However it just seems sluggish setting off etc and even after 1 journey of around 6 miles of use I'm down half a battery. Surely that isn't right? Bad cells in the battery maybe? Baring in mind the battery is brand new and probably a month old now. How can I make it better quicker and more responsive?
Man well done on the conversion that bike rips would love one of these, don't know why they don't make them in a higher power version as stock, maybe sometime in the future these will be out at a decent price. Nice vids smart guy.
question i think is valid for us noobs , i see heatsink/fins can be added to a hub motor to keep it cool ,but can any sort of adjustments be made to a crank/chain powered motor ?
@@andykirby Yes compression & sag no point if you got loads of power if you cannot put it to the floor in a controlled manner. But its your forte not mine.
Hi Andy buddy iv just ordered a cheep Chinese 72v 2000w controller and intended using 6 of the 36v bosch batteries u use will this work to get close to what you have done to this bike ?
@@user-ck6kq8zl2i yes you will kill it for good seen some dodgy youtubes from india doing it to a GY6 engine think the c90 is a classic bike and would leave it alone... Petrol rules for range wont get electric bikes doing 200 miles and a 5 min refill for another 200... we know it will never happen anytime soon
Hey andy just curious if this thing is still kicking you and a couple others are a huge inspiration for me starting my own channel. I have a mototec in the US but ive always like the style of the renegade with the motor seperate from the swing arm 🤙
It would be interesting to see what it does up against similar bike with a gas engine on it! I bet it will smoke the gas engine at takeoff I don't know about top-end because of gearing but even if it's all one gear that thing must turn over some pretty high RPMs and with the right rear sprocket and front sprocket and with that electric motor I'm almost positive you can smoke a gas motor all the way around it's got so much power at takeoff even if you geared it for top-end it would still have plenty taking off. I actually bet it's fun as hell trail riding with it. I want one I haven't looked yet but I hope you put a link to what motor and controller you're using if not please comment back and let me know what exactly you're using for the setup. Thanks be careful and have a blast on that thing I would. I bet you could put that on like a 125 dirt bike frame something bigger 4 people are size and it would still be plenty of juice what's the ride time how long can you run for before it's dead?
