How to INCREASE SPEED from an E-BIKE

today I'm going to show you how to increase the speed from an electric bike to give you a quick sneak peek this is before the modification and this is after if you're new to this channel then make sure to hit that subscribe button all main parts will be linked in the description and let's get started the ebike we'll be working on today is a hyper Eid electric mountain bike now of recently shown how to add a throttle onto it in a previous video if that sounds interesting then I highly recommend to check it out after watching this video well how do we increase the speed from an electric bike let's dive in deeper when we look at an ebike online we can clearly see the difference this ebike battery has a nominal voltage of 48 volts while the one we're working on only has a nominal voltage of 36 volts this makes a big difference since the ebike from online has a top speed of 32 mph while the ebike we're working on only has a top speed of 22 m per hour so in theory if we increase the voltage the speed should increase as well for that I got myself a powerful boost converter which is capable of handling a whopping 30 amps at the input and boosting the voltage up to 90 volts so after removing the battery connecting the battery to the input of the Boost converter and connecting the Boost converter onto a multimeter a question comes to mind till how much can we boost the voltage this question is important since we don't want to fry the speed controller well the answer is that it depends on how much the speed controller from the ebi can handle when looking at the actual speed controller we can see that it is rated for a nominal voltage of 36 volts and while looking at its data sheet we can not only see the wiring diagram for the controller and its programming options but if we look look closely at one of the first programming settings we can spot the option of running the speed controller with a 60 volt battery perfect so now I'll pop back in the battery and enter the programming mode through the display to change the default voltage so that the controller will think that we've connected a 60 volt battery to program the display we have to hold down the power button and mode button at the same time for a few seconds we'll enter the default password which is 4 * 6 hold down the power button for a few seconds and we're in by clicking the power button until we reach the voltage settings we can witness that the voltage is set to 36 volts so we'll press the mode button until it displays 60 volts and hold down the power and mode button to save the settings don't worry about this low voltage error since we didn't raise the voltage yet now that it's set we can once again remove the battery hook up the Boost converter and finally set the voltage to 67 volts which is the fully charged voltage of a 60 volt battery pack when connecting to boost converted to the speed controller nothing blows up nice now I'll power it up and give it a quick test wow 38 mph that is almost double the speed this does not mean that will drive on the road at 38 mph but to find out how fast this ebike will go I have to 3D print a suitable enclosure which will help with both mounting it and waterproofing now that it's done we can start removing the supports before installing the components the first component we'll install is an on and off switch which will allow us to cut the power from the Boost converter that will ultimately prevent the Boost converter from draining the battery the second component will install is a cable gland which will hold the cables in place I'm going to use two self lacking nuts which will be used for mounting the enclosure onto the frame of the bike I'll also install a green LED which will indicate the Boost converter's output State for the power wires I'll use some 14 gauge silicone wire before clamping down the wires I like to Tin the wires with solder to improve the connection now that it's done we can start wiring everything up before closing it up we have to set two more parameters on the Boost converter the first one is the under voltage protection which we can set to the maximum since the battery already features that the second parameter is the constant current setting which I'll be setting to maximum as well since we want the Boost converter to be running at a constant voltage to keep all the Boost converter settings locked in place I'll be using some hot glue before closing everything up we have to remove the bolts in order to be able to replace it with these male to female spacers after that is done we can finally close it all up the final step before mounting it is to waterproof it using some silicone and after waiting 12 hours forit to dry I'm going to create a template out of a sticky note and cut it so that it will fit into the bike's frame now we'll install the bolts and tighten everything down the final thing to do before taking it for a test drive is to connect the Boost converter wires onto the ebike we'll start by running the wires into the hole of which all the wires come together then I'll chop the two wires going to the battery's connecting terminal if you're wondering how I know the difference between the input and output cable then let me tell you that I don't so the only way to find out the difference is by temporarily connecting the battery to one pair and then measure the voltage at the other pair which is 67 Vols perfect now we'll permanently connect the wires going to the battery and connect the Boost converter's output onto the wires going to the speed controller next I'll screw down the battery connecting terminal and then finally reinstall the battery and now that the project is complete it's time to take it for a test [Music] [Music] drive if you're wondering how fast thebike actually is I'll put up on the screen the GPS for my phone and let's give it another go and the top speed is 28.6 mph now while 28 mph is much faster than the original speed of 22 mph just consider the fact that this is only a concept which means you can easily achieve a higher speed just by replacing the speed controller with one that can accept a higher voltage so if
