Frequently Asked Questions
Common questions about MTB bikes like this one.
What wheel size does the Ninety One Thunder come in?
The Ninety One Thunder comes with 26"/66cm wheels.
How much does the Ninety One Thunder weigh?
The Ninety One Thunder weighs approximately 16.3 Kg.
Are mountain bikes hard to ride?
Not really - their sturdy build and grippy tyres actually make rough terrain easier to handle than on a standard bike.
Which wheel size should I choose - 26", 27.5", or 29"?
26" suits city riding and light trails, 27.5" is a versatile choice for both city and off-road use, and 29" rolls best over obstacles for serious off-road and downhill riding.
Can I ride an MTB on paved city roads?
Yes - mountain bikes handle city streets fine, though they're not as fast as a road or hybrid bike on smooth pavement.
How much weight can an MTB carry?
Most MTBs handle riders up to roughly 100-120kg, though this varies by brand and model - check the specific bike's listing for exact figures.
What does suspension actually do?
It absorbs shocks from rough terrain, giving a smoother, more controlled ride with better traction on rocky trails or potholed roads.
