Converting a 48 Volt eBike into a 60 Volt Beast 

First, congrats on the transformation. I like what you have done here. Watts = Volts X Amps 60 volt battery means you likely have 15 clusters of 21700 cells X 4 in parallel for a total of 60 cells in that big Reention battery case....their biggest shark case. As to Tuning because power is proportional to amps with a fixed number of volts, the more amps you feed the controller, the faster you go. But...there are two constraints: 1.What is your BMS rated for? It has to be well over 30 amps....or I hope so because if it isn't, when you get your new motor you will shortchange its capability. 2. your motor windings relative to the amps you push through. If you push too many amps through your stock motor, you could burn it up. Me? I would let it eat because you have a new motor coming. I would turn up the amps on your controller to about 35 amps or so. Just don't run sustained 35 amps but in short bursts it will be fun. This is what the hobby is all about. The butterflies you felt when you played Dr. Frankenstein with your bike is what builders live for. Its partly why we do it. To see, what if. PS. because I peer through the lens of product development, I would likely of solved your battery riddle a bit differently. Two 36 Volt batteries in series for a total of 72volts. One on top of the top tube where you have your big shark and one under the top tube hanging down. Split the baby. Maybe an aesthetic improvement as well because it would look more balanced cosmetically putting battery above and below the frame tube. Just a suggestion for a bit more juice. You could sell your battery on Facebook if you wanted to go in that direction. Just make sure you had big BMS's in the two separate batteries.

Bike is amazing gonna be doing my own soon so I'm really appreciating these videos

looks so professional

I'm hooked on these videos. Great job. I just got the G-Force T42 with 16ah battery and 750 w motor. Very similar bike in terms of styling.

Congrats on 4K!

Clean build dawg, trust me the new motor adds like 6mph. Making me want to invest into a full suspension folding bike

Bike looking good so far. But now that I know you got a ship steering wheel I hope you are planning to use it for your handlebars.

I live in Bucks County, Pa. I wish I could buy an eBike, and pay you, to upgrade it for me. You are very good at these things, and your videos are extremely informative. Thank you! =)

Good job man \m/

Limit the current and you can push full throttle continously without having to worry about the motor hub overheating. Some LCD displays have a current limiter mode, if you set it back 25% then you are at the same level as before. So say your max amp is 30A then set it to 22,5A through your display settings because going from 48->60V is a 25% increase in power.

Dam thats one chunky boy on top lol. Definitely wish they would update the cycle analyst it looks positively ancient, I'm curious if there's any demands for a display similar to a motorcycles I've been looking but no luck

Is there a video where you show the build and not skip ahead 2 days?

I got a bike just like that one but I got rid of the fat tires and put 20 x 2,25 on it with new rims and spokes and it rides so much better because its handles easier im not going to ride on sand or snow. The battery might be a good idea to make it go farther.

I pushed 45A to a stock 500W Super73 Z1 motor for over 2 years with no issues. 36 mph consistently. I sold the bike to a friend and it's still going strong.

Can you tell us or show us how the other connections are made using that controller? The stock controller has many different ends for the throttle, brake sensors, pas sensor and such but the new controller doesn't have these connections that is easy to see or understand. Just curious how everything else connects back up. Wonderful video and thank you for this.

Nice build! Where did you purchase the adapter from the L10 to the smaller pin? Thank you,

Good Vid...DId you put the new motor in and do you have a video of that?

Omg so it was you who put that listing on OfferUp wow what a small world

if ya add a temp sensor, the geared hub can take a lot of abuse, well until it gets to 45c, then the nylon gears start to soften and then you cant push it as far. most i've pushed so far at least is 95A phase and 42 battery amps. you can push 2500 watts! just being mindful of heat ofc, sometimes i have fun and turn it up a shit ton and then turn it down once i get to 50ish celsius. i've also done a controller swap but still on the stock battery, it can take a lot of power surprisingly, just voltage drops a lot though.

My stock 500w engwe does 28 max with pedalling, 24 on throttle.

Good video. How many amps is your new controller?

Looks good and it's full suspension just be careful for the sharp holes they will dig into the wires get some silicone or a rubber inlet to cushion the wires in the holes.

Hey are you running duel battery on this bike or do you plan to in the future? Does the stock battery still fit inside the frame with the top battery holder modification?

Did you change/add field weakening + 10/15amps for higher top speed?

This is the video I was looking for..I have same style ebike and battery that came with it is crap..this is the setup I'm trying and seeing the battery fit on your bike I guess it would work on mine too . Oh by the way can you still fold the bike without any problems?

Do you think it's possible to mount the new battery and have the original battery fit inside tube frame??

20Amps thats crazy, my Shengmilo 48V takes 7Amps max and can also reach about 30miles an hour

does the old battery still squeeze inside? Assume you added threaded flat "washers" into drill holes, but they shouldn't take much room away. If dch009 battery format, they are 13s5p. 16s4p would allow paralleling them.

Was wondering if it's possible to leave the original battery intact and mount an additional one as you have, for a dual or tri-battery set-up. What is the clearance like on the down tube? I'd hate to leave that space empty. @Npl_ventures

Have watched your videos about the Crooked Path E-bike. Was wondering if you have changed to another bike. The Crooked Paths are no longer available. Thanks

Whats that battery case? I got a polly dp9 that fits 91 cells, but yours looks different... maybe larger? The connector ist identical though.

Where did you bought the 60 volts battery?

damn do you have any alternative controller similar or the same thing?

Where did you get the 60 V battery.....?

what grips are those?

What's the amps of the original controller?

Was there not enough room on the under side of the downtube for the battery? Curious as to why you chose the top side instead? It seems like under the down tube would significantly lower the center of gravity of the bike.

With square frames I prefer to use Gorilla mounting tape instead of drilling holes in the frame.

I built a bike battery holder out of electric tape and the computer to

Can I use a 36v battery as a back up battery for my 48v ebike?

I like your voice.

suspension upgrade you mean the front fork?

I have a bike similar built to that but I want to keep the internal 52v battery and get a second external and mount it up top. Do you think there's enough space to install it as you do here with the screws and nuts? Or do you think if I threaded the holes you drilled I'd have more clearance if it wouldn't already fit.

A lot easier to mount batteries and other items to your bike with a Rivnut tool!

Dude, I push 1800W regularly on those old Bafang G060 Fat Motors, drill a small vent hole and use Statorade

what is the battery name?

We purchased this Vivi 27.5” electric bike and a Tentaquil 26” electric bike for our 13 and 14 year olds. ru-vid.comUgkxUiL0GnyDjP32RJdd660sP8mZk4CRLTCJ The Vivi was much easier to put together. With the Vivi, there was a video link to assist with assembly which made the process easier to follow (we did put the handlebars on upside down, but it was a quick and easy fix). With the Tentaquil, the assembly was not as simple to follow, but after we messaged the company for an assembly video, it was easier and they did respond quickly. The other major differences were that the Vivi has a grip throttle on the right handle (like a motorcycle) and the Tentaquil has a push throttle that you use your thumb to activate. The monitors were also different, so if you’re looking for something specific in terms of changing the bikes functions, pay attention to what the monitor offers. We were really impressed with the overall quality and functionality of both bikes, but if you’re looking for more power and an easier assembly, definitely go with the Vivi!

Curious to why you aren’t considering a direct drive. Then you could really push it without having to worry so much about heat build up. Either way, awesome build. Can’t wait to see how that motor holds up.

whats the range ?

I'm looking for someone to show me how to put one of these together in exchange for cash. .I'm near Atlanta. Are you anywhere close by ?

Only 60 volts?

Careful that controller doesn’t get too hot in there.

What phone is that? Oneplus 7 pro?

If you want real speed improvements, you need to go 1500w 3000w 72v and an 80A controller. Gear motors are not very good for high speeds.

OK, already in the first few seconds I am wondering if it is a statue or real dog. He is sitting really still.

Wait the top speed was 31 mph? That's all? My 750 Watt 48 volt EUY F6 can do 28.

Why the helmet in the video

So you converted to 60v at alot of expense and time, yet still only getting 1000watts and the same speed as a 48v system, also, you pretty much replaced all the ebike parts so why not just get a standard bike and fit it all to that ? I have a engine pro and can get 31mph from a 48v 1000watt peak and not worry about burning my motor, seems like alot of expense for no gain

I see it’s a Mosquito helmet.

FIRST!!

You did a great job and your Ingenuity is incredible but the battery on top looks ridiculous, looks like a tumor.

Fix your title. You didn't convert anything. You replaced the 48v system with a 60v system. Learn your grammar.
