Dataset
This data set includes details about individual rides made in a bike-sharing system covering the greater San Francisco Bay area during the period from April to June (spring 2020).

Summary of Findings
Most of customers were casual customers, and most of bikes rided were electric bikes.
Casual customers who used docked bikes have the heighst chances for having a very long trip. While members who used electric bikes are related with the least trip duration.
Number of trips each week increases over time.
Visually, there is a potential negative correlation between number of rides per week and mean ride duration, however, further analysis is required for assessing this relationship.
To watch the final visualization slide show: download and open 'slides.slides.html' file. For more extensive details, you can check 'exploration.ipynb' notebook.

Key Insights for Presentation
Proportion of users in each category.
Proportion of bike types.
Effect of user/bike categoty on trip duration.

Have been working with Ahmed for quite some time now. He has delivered all projects as per the requirements. Makes sure all doubts are cleared before the start of the project and delivers great work. Expert with python and machine learning algorithms and applies logic to the work which has been really helpful. Always available for changes at a later stage. Will surely keep working with him.

Ahmed Mahmoud did a great job troubleshooting my problem and also did a great job of cleaning my code up. Always very quick to respond and was very polite. I took a gamble using someone new with no previous feedback, but was well worth it. Would recommend.
