There are dongles for certain ebike motor brands that can do that. For example, you can explore the German bikespeed site to find out which brands work with their dongles: Bosch, Yamaha, Brose, and a couple of others. There are several other dongle makers, but in general they address the major ebike manufacturers only. You will have to provide more specific information for people to help you: motor brand and model, etc.
Be aware that using such dongles probably voids the bike manufacturer's warranty and, depending on where your son rides, they may violate local laws as well.

Thankyou for the info. I did not see this motor in the list. its a china bicycle

Thay all are. More details please, motor brand? A display manual? Exact brand and model name?p how fast or slow is it? What voltage is the battery.? Have you tested the battery voltage with a multimeter? The devil is in the details

First I will tell you straight up IMO ebikes are not for kids under 16 and faster ebikes are only for adults with training.
Not all ebikes allow the user to change the set class speed and those that do require a code from the manufacturer.
Changing settings can damage the ebike so be careful what you change and write down the original settings in case you need to reset it.

Have a Vivi c26 500 w 48 v coming via fedex tomorrow. Photo bomb and specs on components tomorrow. Rather than create a new post, I'll just keep this one alive.
So A bit about my background, near 50, rode motorcycles since I was 16. Stopped riding motorcycles about 10 years ago. Before that I rode Honda mopeds like the spree and elite. Ridden other brands before as well. Rode one of the first E-Bike brand Ebikes, sorry I can't find photos or specs(it was in the mid aughts), but it was one of the first ebikes commercially available in the USA. Put together my first gas powered bike years ago because I found the ebike too slow. So, have to start out by agreeing with Solarcabin, for those who have never ridden any kind of motorized bike, motorcycle, scooter, or gas/electric engine bicycle, trust me, 20mph or 32 kph will be plenty fast enough for you. I know a big guy who couldn't handle driving a moped at 35 but found the slower speed of an ebike just perfect. In no world, would I help a 16 year old or younger make anything with two wheels go faster. Driving a cheap walmart mountain bike with a gas powered motor at 35 mph is fun, but also terifying, cause a regular bicycle was not designed to handle those tollerances. Never mind motorists and everything else you have to worry about including breaking distances.
Now for op,
Where there's a will, there is a way, and there's always a f@cking way. So, if you're ok with a voided warranty and possibly ruining your ebike, proceed to mod. As I understand it (hope I'm wrong), there really isn't a way to bypass or alter the speed limiter without actually hacking the software and/or probably modding the hardware in both the controler and hub motor. Some one knows how to do this; in time, I will know how to do this. Right now, would love to hear from somebody who knows a guy who knows a guy who knows how to do this. I doubt very seriously, simply messing with sensors is going to be a long term viable solution. Trust me if it as simple as cutting a wire or slightly modding a hardware component I will figure it out, but I susspect it's not going to be that easy.
Things to keep in mind. No offense to Vivi, but this really is the poor man's ebike. For comparison, One should expect to shell out at least 1 to 2 large(that's $1,000 to $2000 usd) for an entry level ebike. When you take out the cost of shipping, this is really a $300 ebike. You get what you pay for; in this case probably more! But seriously, the bike light I want costs as much as this ebike with shipping. So, be realistic. It may just be in your, mine and everyone else's best interest to simply accept we're better off not tinkering with this model at all.
In the end, I don't want to frankenstein my ebike(no offence to those mad scientists creating their own monster ebikes, I respect and salute you!). I want the speedometer and all the pedal asists to function as they should. I am buying this bike because my knees will not take up hill pedalling, i'm in a rural area so its up hill both ways in any direction and it would actually cause me more pain to get off a traditional bicycle and walk it up a steep hill. That's it, I just need uphill asist. Spine surgeries and shoulder surgeries, no, I'm not going off road with this bike, except to cut across manicured grounds. I imagine some one has already won a Darwin award for treating this $300 commuter like a $1000 mountain bike.
Having said that I have a grocery list of accessories and simple upgrades planned. The (non) ergonomic grips with the half twist throttle will be the first thing to be replaced, with classic cylinder shaped grips with full twist throttle.
Would love to hear from others. I'm hard boiled, there are no words in any language that will hurt my feelings.
To op and others, I'm not going to tamper with the speed limiter unless I can keep the other functions that may be tied to it. If there is a way and there always is, I'll figure it out. We'll find out. Photo bomb and specs tomorrow.
Edit: As I posted in another thread, bike came, but there is an issue with the front wheel axle. They sent the wrong one. So, I'll update as soon as I can get the front wheel on.

Ok, got the bike, got her running and you better believe I'm going to figure out how to disable the limiter. It's not a matter of speed. Don't get it twisted, I'm over the moon happy with the bike and going only 22 miles per hour, but in cruise, you can feel the limiter fighting the hub motor at 20mph. I'll figure this one out. Also, again at this price point, I feel I have no right to complain, but she has some of the ugliest welds I've ever seen. I'm not sure I want to test the tolerances on this bike at 30mph.

If there is a way to do it, I'll figure it out just to get rid of the annoying fight in cruise. It's jarring and doesn't feel good at all. Similar to bad abs or traction control on a car when you don't want it. Having said that, I'm so far away from having the technical knowledge to hack the bike, there will be no attempt to do so in the near future. I agree with everything you said.

@February, I was restraining myself from expressing my views on the matter. However, I'd like to help you understanding what e-bike is and what it is not.
First of all, what would be the speed you could achieve on a traditional pedal bike? Now, any speed higher than that achieved on an e-bike is your gain. One of the most dangerous myths new e-bike users believe in is an e-bike is a moped or a motorcycle. It is not. Were you a sporty, young and healthy person riding a racing road bike, you would probably ride at a high speed on your own leg power. However, a flat bar bike is capable of reaching the cruising speed of 18 mph at its best, and anything above 20 mph is hard to achieve because of the air drag.
Now, you feel bad because riding full throttle with several hundred watts (which is what only a pro cyclist can achieve with their own legs) takes you at 20 mph and beyond the speed limiter so easily. What if I told you e-bikes were limited to 15.5 mph in Europe, and there are millions of e-bikes here? Yes, that's the fact; bikes usually do not travel at 20 mph.
My only advice is reducing the assistance and riding at 18 mph max. It is a good cruising speed if you do not expect riding a motorbike.
One of the baddest crashes of mine occurred just several days post my first e-bike purchase (it was a $1,900 e-bike, very cheap as for Europe). That e-bike was factory derestricted (so illegal here). I rode at 19 mph and tried to overtake a traditional cyclist. The crash was bad and I was lucky I didn't turn into a vegetable, especially as it was my single and only helmetless ride. I made 28,300 miles on e-bikes since and understood the e-bike is in fact a bicycle that is easier to pedal, and which is marginally faster than a bicycle.
Enjoy your rides and thank you for your attention!

Glad you recovered. I appreciate your feedback. I think it will be more helpful for others, because you and I are already on the same page. Maybe I'm just getting old, but 18 to 20 mph is fast enough for me. I've done gas powered builds in the past and I've rode mopeds and motorcycles since I was 16. While I would like more speed at times, I've accepted the limitations of the model I bought. And honestly as one youtuber put it, the only con he saw about switching from bicycles to ebikes was that people were losing the joy of a chill relaxing ride and all the mental benefits that come with. In a way, the speed limitation forces those of us with a need for speed to slow down a bit and enjoy the journey more. And you know what, I'm not just ok with that, I see it as a major bonus. There are so many gorgeous views were I live and I'm about 3 miles from a nice rail trail.
