Everyone starts somewhere right?

Hello wazuans,I'm a 19 year old campus student,I'm currently running a viable farming project on leased and I would like to spread my risk on Some other doable investments. Doable in Reference of I being a student hence would venture into something that doesn't take much of my time.

I have identified a bikes hiring business seeing it having boomed pretty much around campus,JKUAT juja. I'm one of the regular customers of these guys,they hire these bikes at 50/- an hour,leaving your school or national ID as assurance that you'll take the bike back. They operate from 8a.m. To 7p.m. daily meaning they are in operation for 11 hours. They hire the bikes overnight till 9a.m. from 7p.m. at 50/- only.
Assuming the bikes operatess for 5 hours that day,that's 250/- per bike per day,And let's say I own 10 bikes that will cost me about 80k to purchase(must not be new) ,rent and kanji probably 20k,total 100k.
With 10 bikes,that's about 2500/- a day,17500/- weekly,70k monthly.
The deal I'd work with the employee,just like it in the matatu business,is a daily return of 2500/-,anything higher or less is onto him.
Maintenance costs and rent,to the higher end might cost an average of 30k,40k profits On average?
I plan doing it around some other campus not necessarily JKUAT. I have identified Embu/Kirinyaga/Karatina universities since I have friends around and would be easy to monitor. Visits,every weekend. Also,planning On adding more bikes with the profits.
If I Start,planning on first operating the business for two weeks to know the market activity.

Is this possible or does it sound unrealistic?
Regards

Its a new course, Bsc Innovation technology management.
jealous?

Go for it, sometimes you have to throw yourself in there to know if its possible or unrealistic. Am totally impressed with you, at 19 every coin i saved was used in a bash.

Thanks you so much for the advice,I am considering this as my second venture since the farming project rakes in cash after some few months thus the need Sth that gives cash daily or weekly.
Also,on NSE,I'll sure need proper guidance on that,been following threads here on Wazua and I think I'll get there Soon.

I don't pay my own school fees for now,but I pay my own rent(my parents know I Live in the school's hostels).
The projects above aren't sponsored by my parents directly,my savings and also Started out with loans From friends and small partnerships with them.

I am not up for white collar jobs tho I make sure that my grades are good every semester. Sadly,the old man is in HDU in Nairobi West Hosp,makes me scared and wanting to invest more.

What motivates me is the thought of being independent,calling my parents every week for a small allowance is depressing.

And again thanks ya'll for the kind words.

My advice. Concentrate on your studies 100%. These short 4yrs can make a huge difference and determine whether you live the rest of your life as a top executive or as a "hustler". This is the time to unleash your maximum academic potential without any distractions. Do the best you can academically. And you will have all the time to engage in any business you so wish after graduation. There is a time for everything. A time to study, a time to trade.

As someone said up there, those who are always hustling in campus on side business mostly end up hustling after campo since their grades suffer.
