Do you know what this doesn’t look super practical; however, this is very creative! Hopefully our battery technology will improve in the next few years and things like this would really be something else. I myself would prefer the steam powered bicycle that you can cook your dinner on
Estimating - Probably a 20v drill and assuming a 4 amp hour battery I estimate 7 to 7.5 miles. Top speed is 25-28 mph for a couple of minutes if gearing is right. Cruising speed probably 15-20 For Distance - I'll assume 4 amp hour battery. Most 20v drills make about 500 watts (hard to find info), so they are pulling 25 amps. At full speed putting all that power into the bike it could last maybe 9 minutes. He looks like he is going 15 mph. 2.25 miles. In reality though, its probably only using half the power, and half the time one is coasting, so 2.25 * 4 = 9 miles. Take 25% away to account for efficiency. So Probably 7 miles. I used a bike distance calculator online and it said 8.6 miles with a 24v system. Drill is probably less efficient so probably 7.5 mile or so this way. For Speed - I used a bike watts calculator to maintain a certain speed at 400 watts one can sustain 25-28 mph. If the drill has 500 watt max capability its only so efficient so I'm just estimating 20% loss or so. I think that would only be possible for a minute or so before battery drain lowers the output.
my 20v batteries only run about 10 mins straight, so maybe a mile or so if you are lucky. also remember, this thing is straight geared, you can't coast and when your battery is out you're pretty much done unless you wanna pedal against the motor.
Bien.buena idea. Tambien puedes colocarle un par de barritas en el cuadro de la bici mas al frente asi no tienes los pies hacia atras y tienes mas apoyo.
O problema é que a parafusadeira trava quando não é acionada, isso significa que se a bateria acabar vc tá na mão. Se colocar uma catraca, dará pra colocar pedal, mas ela não poderá ir pra trás sem ter que erguer a roda
ive seen this done at least 6 times before and this is the best by a mile and the easiest, and some others you cant pedal only the drill powers it, and yes the large cog will shark fin in a while but most don't use it just the smaller cog and bike parts are cheap if not free on council pickups,
Show de bola MAn !!!!! Parabens pela feito e trabalho MAn ! Ai nem esquenta com algum comentarios DEPRECIATIVOS porque grandes inventores do MUNDO tambem foram DESACREDITADOS. ((((Maximo.Respeito))))👊
I think it’s the gear ratio is wrong what do u think 🤔 And y did u cut off the other crank arm? Where is your other foot supposed to go? I love the video thanks for a great idea I will post mine once I get it designed Remember the ppl that hate or dislike aren’t True inventors inventors make solutions Still don’t know what the haters do lol 😝
@@mr.engineear0987 i've never heard of a "reducer" motor used in a handdrill.. it's likely a brushed or brushless motor used in one of those.. and i have had one catch smoke while using it during drilling.
3/4 mile - 1.5 is my personal guestamet, I don't think that it would make 2 miles. Cool & ingenious idea, just not very practical. Nice to know that these things are possible though. Cool video 😎😎😎😎😎👍
5 mile range per charge??? Did you use 1.5 or 2.0 ah batteries??? Are you familiar with Stanton, Inc? They make an interesting 2 to 1 gearbox for drill powered bike? Interesting stuff.
Every thing is backwards the throttle on the left hand side and you have to twist it away from you no peddles and a battery that will take you down the road and maybe back if you’re lucky
