determine your team size

Determine your team size

1.Each team is formed by at least 4 members.

2.There is an upper limit to your team size which is calculated on the basis that each team member pedals the bike for at least 30 mins.

3.For example, if your team would like to take part in 3 sessions (i.e. 6 hours), the maximum size of your team should be 12 (i.e. 6/0.5 hr). 

4.If your team has 5 members, the total pedaling time is at least 2.5 hours (i.e. 5*0.5 hour). Therefore, your team must sign up for at least 2 sessions (i.e. 4 hours). The maximum team size for 4 hours is 8 (i.e. 4/0.5 hour). 

5.Similarly, if your team has 10 members, the total pedaling time is at least 5 hours (i.e. 10*0.5 hour). Therefore, your team must sign up for at least 3 sessions (i.e. 6 hours). The maximum team size for 6 hours is 12 (i.e. 6/0.5 hour).

Donation calculation

1.The suggested donation amount per session is HK$800.

2.The suggested donation amount of 2 sessions is HK$800 x 2 = HK$1,600. And so on.

Min No. of Hour = 10 x 0.5 hour* = 5 hours

Min No. of Session** = 5 hours /2 hours = 2.5 sessions

 *Min 0.5 hour(30 mins)/person

**2 hours/session



Our team has 10 members. What is the minimum number of session we must sign up?

Pedaling time per team member = 30 mins (0.5 hour) at least

Total pedaling time for a team of 10 = 5 hours

Given each session is a 2-hour unit, a team of 10 will have to sign up for at least 3 sessions.



Suggested Donation = HK$800 x No. of Sessions 

8 hours = 4 sessions

HK$800 x 4 sessions = HK$3,200

Suggested Donation HK$3,200

Min pedaling time/person = 30 mins (0.5 hour) 

Max no. of person for 8 hours = 8 hours/0.5 hour = 16

Max Team Size: 16 

Our team wants to participate for 8 hours. What is the suggested amount and maximum number of members we can have?

Suggested donation $800 = HK$800 x No. of Sessions

8 hours = 4 sessions

Therefore, the min donation amount

= HK$800 x 4 sessions


Max team size = 8 hours/0.5 hour = 16
