First Ride Impression
I Got the Bike Delivered Super Quick Qudos to the Team, Thanks for the Code The Cycle is of Top Notch Quality and is super Smooth it just flyes Howevr the Seat has Very Less Cushion which is a Cause of Worry and in 15 to 20 Mins Ride You start feeling sore or when potholes are there its bit annoying and not that comfortable I will definitely chamge the Seat Else Everything is Top Notch

Frequently Asked Questions
- General
How can I try the bicycle before I buy it?
If one of our many distributors is located close to where you are, we recommend you try taking a test ride of your preferred bicycle. You can use the store locator to find out which is the nearest store that you can go to: Store Locator. In case there is no store close to you, you can pick the right bicycle on the website. The website features all the tools and assistance required to make your purchase seamless. We also have a host of images including close ups for all bikes from all possible angles for you to explore. And we are proud of our cool AR (Augmented Reality) feature for a couple of bikes to have a real life experience of the amazing Ninety One bikes whereever you are!
What is the meaning of MTB bike?
A mountain bike (abbreviated MTB) is a bicycle designed for off-road cycling. The heavy-duty construction combined with stronger rims and wider tires has also made this bike type popular with urban riders. It is a great way to navigate through potholes and over curbs. A mountain bike is a great buy for all those who are looking at going on off-roading adventures as well as for those who are going to use their cycle in the city to enjoy their rides bump-free.
What is the difference between a hybrid bicycle and a MTB?
A hybrid bike combines the features of the road, touring, and mountain bikes. Perfect for those on the fence who wish to go for something comfortable and versatile, hybrid bikes are great for multiple surfaces. MTBs or mountain bikes are specifically designed for off-roading experiences and are great to ride on steep slopes. These bikes boast a stronger frame and often feature front and rear suspensions which help in off-road performance.
Are MTB heavier than the road bike?
Yes, MTBs are a little heavier than road cycles. However, you need a heavy-duty and stronger framed bicycle when riding off-road and on steep hills. Mountain cycles are meant for a more rugged use and are extremely rider-friendly. They offer you the right amount of safety when riding on a mountainous slope. Their wider tires and larger suspension is what makes them heavier.
Why should I start mountain biking?
It's a great activity for the arms, back and legs. You work your heart but you're not hurting your joints it's very friendly on the body. Mountain biking pushes your workout routine and cardiovascular activity to a whole new level. Moreover, it is a great form of adventure which allows you to explore the region like you would never otherwise be able to. Mountain biking is a sport but it can also be pursued as a passion.
