These clearly break the design rules that limit electric bike maximum power to 500W, so it doesnt seem like the laws on the books are being applied any more. You could have 40Ah, 100Ah or 1000Ah - it would make no difference. An electric bike is de-restricted by placing a compact electronic device between the sensor magnet of the wheel and the computer that calculates the speed at which you are moving. The sensor is the device that reads the behaviour of the bike and translates it to the computer unit or the controller. Working out just how high I could safely push the voltage was a dilemma too – if the only feedback I got that I had raised it too high was a broken motor/controller, then that’s hard to plan testing around. It has 14 Cells of 3.7V 50Ah. Note: Check with your local regulations before adjusting the e-bike’s speed limit. Verified and Tested. Speed controllers are sometimes called in electric scooter and bike owners manuals a: control module, module, brain, brain box, control box, Voltage controller, or controller. It has about a 2A limit. The children cheered! Deal. This insufficient speed limit has therefore been a matter of concern, but it should not bother you too much. More ordering and multi-month delays before I could work on it again. ... 10 might be the speed limiter. I think I'll try to aim around 4v/cell. It was just the external cabling that broke. Putting on some monitoring to see what was happening, I could see that the battery voltage had some deep sag whenever the throttle opened up. SHOW DEAL. The endless war of ebikes continues. Above 45V, initial conditions and weather was still influencing the performance, so it felt like higher speeds might be possible if the road was longer/flatter. Get all information about the latest events, specials and offers of the day. I’m an electrical engineer with a background in solar car and EVs, so I was comfortable in looking into this as a project. Top speed was like 22 mph on the 36V battery, using a bike computer calibrated to the actual … There might have been some adverts inflating the speed you can get when you derestrict to such numbers as 75km/h. So even with the bike controller off, the DC converter was pulling short circuit current. To put it simply, if there must be a lower frequency to be noticed by the controller, then the device must be transferred to another place. E Bike Tuning for Bosch Active, Performance, CX and Classic, Panasonic, Brose, Impulse and Yamaha motors. If your aim is a higher top speed, then putting all power through a DC/DC boost is the best way to go. The handy method works only if your electric bike allows it. The multi-kg battery pack, loosely held in with a single tie-down strap, launched to maximum height before coming down on me and the crumpled mess of a bike. Buying them cheap off ebay meant a 6 week turnaround for every purchase, so with setbacks, this took over a year to do the design and testing. It not only prevents them from having the full experience of the electric bike, but it also limits the fun. Since the drive uses how fast the rider is pedalling to decide how much drive is released, it can be manipulated to think otherwise. As long are you are in control, speed can be a thrill! I have 24V 100Ah lithium battery. They were just too heavy and old. These kits are categorized into two – the ones that need disassembly and the ones that do not.

Now to find a bms for the turnigy packs I guess.. I put this on a beach cruiser and it will run 20 on flat ground with the speed limiter disconnected, under 15mph with it connected. Related article: An In-depth Comparison: Electric Bike Vs. Motorcycle. Initial tests were all successful, but I couldn’t go for more than a minute without the DC converter going into a weird state again, and no longer providing power. In using this method, you do not have to disassemble the entire electrical system. Follow the instructions below to adjust the top speed of your e-bike directly from the LCD Display. I dont think the seller knows what he is talking about.If you have a battery pack with too much voltage, then yes, you could overheat a converter(or any kind of circuit, ie your motor) because it will draw too much power.But if you have a fixed voltage(ie 24V), then it doesnt matter what capacity the battery is. If you have ever sat on or rode an electric bicycle, you would know the feeling is a real one. We have integrated our customer's wants and desires, into one scooter. This bump was enough to jump the front axle out of the forks, bringing the bike to a dead stop and causing me to rush headfirst towards the pavement. Electric start, improved carburetor and all of the standard safety … Some electric cycles are made for riding on beaches and across hilly terrain, while many others are designed for navigating around the busy sidewalks of a big … I took full notes, with pictures, and ‘proved’ to the supplier that the booster was actually faulty. While the sensor is located on the frame bases, a magnet is located on the rear wheel. An electronic bike is made to monitor the speed at which its rider is moving. That’s probably because its not a great idea™ for the correct way to design an ebike. The effect is you have an initial burst of speed but within a few seconds the stiffening is gone and the battery voltage is down to a lower level(as is the speed). This is the guide that fuels most of the de-restricting options that are available. The other method that exists is quite technical and can cost you a lot. I pulled out my ancient stand alone GPS and taped it to the handle bars. If when riding it seems like the power backs off as soon as you try to accelerate, then this is probably the current limit kicking in. This slower speed is what the system reads and, as such, it prevents the limit from being triggered. Attempts to re-bend the forks were just damaging the bike frame. After that, the controller determines the amount of assistance that must be provided by the motor. However, depending on your needs, all of this pales in comparison to being able to enjoy your bike at full speed. Yesterday I built 48V pack. Manufacturers will not repair or have anything to do with a bike that has been derestricted. Remember to wear proper safety gear. It was down to near 20V for full throttle. 4 years ago. For each run, I would memorize the speed and voltage at the 2 points, then write them into a log book at the turn around point, and do the same on the return journey. Is the electric bike good for the environment? Each state is responsible for deciding how to treat such a vehicle and currently all states agree that such a … A method for measuring repeatable results was still eluding me though. There was only the odd lingering parent that thought coming to my aid might be in order. The controller get power from the battery and channels the right amount of power to the motor. The general rule seems to be that under 500W, torque washers will do, but above that, torque arms are required. I waited 6 weeks for it to be delivered, then gave up and ordered another one. I dont have the original link, but I googled the description I included in the instructable and it was the first hit.What is the voltage rating of the motor you are driving? The seller says more than 40Ah input over heats the converter and kills it. This is a misguided and incorrect notion. Kudos to you! Reply As long are you are in control, speed can be a thrill! In some bikes there is the possibility to remove the speed limit. The two measuring elements up for consideration here are the sensor and the magnet. I want to convert it to 36V. I decided that 52V would be my maximum if I was make this a permanent setup. If you set it to maximum charge rate (45V) then you would have it a bit higher, but you'd have to take steps to make sure you never forgot about it, or you would cook your batteries.By putting it all through a DC/DC converter, there is no upper limit. Professional bikers are a huge part of the populace who feel concerned about this limit. One can imagine how it will feel to have your bike tripping off while hitting the core of your practice simply because the bike has reached its limit.

Useful if you have a low battery and want to increase your range by keeping your speed … If I buy a 48 volt 10ah battery will I get much more speed out of my bike? Derestricting, otherwise known as tuning, is the removal of your bike’s pedal assistance limit. So, no, it does not change the capacity of your motor; it only circumvents the prescribed 25 km/h limit. A downhill cruise, you certainly can go faster than 20mph, you are just not going to get help from the motor to do that. Once this is done, the controller will begin to receive a lower speed rate which will ensure that the speed limit does not get triggered. I would regularly recharge the battery and re-do the same voltage setting on a different day to try and get an average sampling of results across different conditions. For simplicity, you can just wind this to maximum. You shouldnt be adjusting the voltage if you have set that correctly.If this doesnt work, post a simple block diagram of how you have set up the power, and I will see if I can spot the problem. I put a hand on the motor and controller between tests, and they were never too hot, but these were also fairly short testing cycles. 4 comments. For just $20, you could convert any existing ebike to use a constant voltage DC/DC converter to increase overall top speed. Cables and connectors (capable of handling high amps, 50A+). I had some aged 7.2AH 12V lead acid batteries lying around, so I made a quick setup using them. It didn’t appear that the twisting of the wires did any internal damage to the wheel hub. The limit is there to prevent all the electrical power from your engine from getting released. However, as a result of how practical they are, it is often possible and easier to return to the default mode should you desire to stop derestriction. The effect is you have an initial burst of speed but within a few seconds the stiffening is gone and the battery voltage is down to a lower level(as is the speed). While I could generally demonstrate that increased voltage made the acceleration and top speed higher, I couldn’t say by how much. I looked at the bike forks, they were now giant Vs. The 2020 All Terrain R750 BASE is currently available for pre-order for October/November delivery.This first shipment has limited quantities available and we expect it to be fully sold out at the time of arrival to our warehouse.

If you arent sure which way this is, its generally clockwise, but not always. If you were to apply a voltage to always keep the batteries at float(2.25V/cell) then you'd have a maximum of 40.5V. So, by tuning to remove this limit, this power gets released and utilized which leads to your bike moving at speeds higher than its previous limit. I was given a 26” wheel hub motor and 500W (36V?) Share it with us! The downsides are that this method will kill your battery pack even faster(if you’re already having aged battery voltage sagging issues). At 2.25v/cell my 13s pack wouldn't even get past my controllers LVC. The cheap and nasty solution was to buy a single 9mm spanner and cable tie it to the frame. Speed controllers for some older model electric scooters and electric bikes may be discontinued and not available. It shows 4 lines of the readings, which is the samples of 2 locations in the 2 different directions. The main data is in the graph. Yes, it is that straight. Alas, the fault was in the DC/DC converter, not the ebike controller. We produce only the best, industry-leading scooters and e-bikes. 20% OFF. The aim here was a higher top speed, not a higher efficiency. If you desire to derestrict your bike, you have to understand that you are solely responsible for the consequences that result from the derestriction. You could stiffen the pack during use with a boost, but make sure it is disconnected when you finish riding.I've done some pack stiffening on my kids ride on electric cars. Everything was rated for less than this – breaker, converter, power meter, connectors and battery pack. However, the crux of this method is the sensor. ‘500W’ 36V DC ebike motor and controller. My alternative is to have the main pack with 18650's actually charge the turnigy graphene packs I have, as long as the diodes are correct the regen should work and the boost unit shouldn't trip. This device causes the computer to calculate based on falsified signals thereby leading to the slower current speed. I.e. So you would place it between your battery pack, and your motor controller/rest of the bike. The limit does not come with the machine itself, it is placed by the manufacturer, and this is why it can be tuned. Ancheer Official outdoor & sports shop, selling high-quality health products such as electric bicycles, electric scooter, pro stunt scooter. This is the speed limiter wire. I already had another one from a separate set, so with one of them on each side, I reassembled the wheel to the forks, wedged on the spanners, and cabled tied them on. This is because it involves the cutting of wires and you may not be sure which wire to cut. I experimented with leaving the voltage high, but reducing the current until it started to affect performance. In all cases, the throttle is limited to 20 mph. It uses this speed together with how fast the rider is pedalling to determine how much drive it releases. I was actually breaking neighbourhood speed limits when I decided to really go for it full throttle. Designed for 24 Volt motors up to 600 Watts and and 36 Volt motors up to 900 Watts. An adaptive bike includes an electric drive system installed on an ordinary bicycle. He made a hasty purchase of it online, not realizing that it didn’t come with a battery(hence why it was so cheap, eh). They are mostly numbers on papers. If the bike has a display you can do a simple trick of changing the wheel circumference to a smaller number. I still wanted to do measurements, so I scalped a 20A DC load power meter from another project, and changed the wiring so it could be put in line. Remember to, https://epiccycles.ca/wp-content/uploads/2019/06/AdobeStock_121302241-e1561537056518.jpeg, https://epiccycles.ca/wp-content/uploads/2018/02/epic-cycles-web-300x138.png.

Ecotric Vortex 36V/9Ah 350W 7 Speed Cruiser Electric Bike $1,099.00 Greenbike Electric Motion Alpha Speed 36V/10.4Ah 250W Folding Electric Bike Also, some clever packaging would be required to permanently mount the dc/dc converter so that it still got the required airflow but was protected from rain. Other times, you can make use of an E-bike because you want to have fun riding a bicycle. What I needed was a way to keep the input voltage to the controller at the maximum rating at all times, regardless of what the battery voltage was doing. Once I took it to work and put in on a kw load bank, problems appeared. This way, the voltage the ebike sees is always the maximum allowable voltage, and you dont see any voltage sag from heavy use and battery discharge. Thanks for putting this up it's given me many ideas. With my 3rd major attempt, I made everything more secure. For all my ebay purchases, I’ve had a 0% success rate on products being resent with no ebay ticket forcing them to do so. It looks like you have a DC/DC converter that has 2 different inputs for different voltage ranges. Hi there , I purchased a 1500 w 30amp dc to dc converter and don’t know how to wire it to the ebike can You post what wires has to be connected from the converter to the ebike. I calculated that up to 45V should be completely safe. This is the basic principle of tuning otherwise known as de-restricting. If you are prepared to stress the components of your controller and motor, you could increase it up to 80 volts(with this DC/DC converter) with a top speed I would estimate over 60km/h. The maximum speed that can be attained, with assistance from the motor, is 20mph. Related article: How an Electric Bike Works? If you dont have a multimeter to do this, then setting this up correctly will be very hard. Can you post a few pictures with this booster wired to ebike controller I have tried that what you said and no changes or maybe i have Faulty booster , but with some pictures and booster connected to the ebike controller , I could see if I have it right. For many people who love electric bikes, this speed limit is insufficient. Hello RamK,It doesnt make sense that you are told you cant use 'greater' than 40Ah battery. Hi elec, Thank you for response. So, I still stand by my original statement. maximum power drawn by motor will be less than 500W. I didn’t specifically measure the relative power/speeds, but the general sluggishness of performance had me backing off on the throttle until it hit the constant voltage threshold again, and then adjusting within this setting to get the maximum zippiness. You can see that, in general, the higher the bus voltage the higher speed at the same location. After browsing a few DC boosters I settled on a 1200W 20A 6V to 80V converter. I trust it for the fundamental tasks of movement measurement, and it is more expendable than using a cell phone GPS app if I crash again. As a result of these growing concerns with regards to removing the speed limit of an electric bike, some manufacturers have taken it up for consideration. At low voltages, readings were quite steady state at the measurement locations. So with it, a fuse, the battery pack and the wheel installed on the bike while it was free spinning upside-down, I did some tests. Keep in mind that you can actually go faster than 20mph, but that will be in a situation where the motor is not assisting you. But before then, what is de-restricting? I assessed what went wrong, and thought about repairs. The two measuring elements up for consideration here are the sensor and the magnet. If I was doing serious research into this I would have done that, but I could get by with static readings committed to memory for now. $15 Off Ecotric Speed Limiter Coupon on Orders Above $45.

The latest generation of 60cc mini bike engines are faster, torquier, more reliable and even easier to set up and start than ever before. Since it is mechanical, it is often explained in different ways by different experts. Simply faster up to 50 km/h motorassisted. The approximate 15% energy loss from conversion may be worth it if you have spare battery capacity for your average journey, and you value the increased top speed and performance more. Verified and Tested. Max setting = no limit, otherwise it will cut power once you reach that speed. The Ah rating of a battery is how much capacity it has, not how much power it delivers in an instant. Web Design &. It also revealed that one of the locking torque washers(part of the axle) was actually installed backwards, and this is unfixable without chopping connectors(assembled wrong in the factory). I replaced it, and then plugged it back together again. Show's over kids, go home. It meant that the controller was well under its 500W rating, and rotation speed being proportional to voltage meant it was equally low. If your aim is a higher top speed, then putting all power through a DC/DC boost is the best way to go. Ordered 14S BMS and 48V controller. Due to high demand across all of our electric bike lines we are working as fast as possible to increase our production speed … When an electric bike hits this speed, all the fun, the juice and the zeal of riding are turned off as the bike refuses to continue accelerating. Often, many e-bikers believe that derestriction causes their motor to suddenly be more powerful. 55V can give me a higher top speed than 45V can. I set it up to try and do a max torque test by measuring the voltage dip while driving it into a solid wall. If you can make it spin with the wheel off the ground then you have set it up correctly. If your bike is too slow blame your choice of battery first. With the extra cost and effort to make it work, he gave up and bought a premade bike, and donated the kit to me. This assumption was correct, and the DC converter rarely tripped in the same way again. Cars and pedestrians were not expecting a bike to be going that fast, and the existing bike brakes were underpowered to stop me in time when things came out in front. You should adjust that higher.

The tool kits, just like the handy method, are also guided by the same principle of manipulating speed rate and distorting speed data. As such, by moving the magnetic device away from the wheel to another element, you can change the number of turns made by the magnet. Yes, NiMH or Li-ion would have a different range. This is because the bigger the wheel, the faster the bike moves. This is the principle guiding the tuning of e-bikes. Derestriction of an electric bike does not make your motor more powerful than it already is. Now to figure out the diodes I need =). So in terms of riding discipline, this was a good method of forcing me to pedal hard during the high power starting torque conditions, and only using the motor to boost me up to ‘faster than I can pedal’ speeds. Up to 45V, the bike had generally reached top speed/power on the run(about 1km total). Sorry, I no longer have the bike set up to be able to take a picture of it. Some more changes in wiring layout, and I had the converter in a plastic box on the bike frame so that the FET heatsinks got some airflow during movement. BMS AND controller cost me about 80 USD. But the seller says the battery Ah should be 40amps or less.
