ABOUT US

Our Journey

 

My name is Vincent Inman, after retiring from a 35-year career in the motor industry due to arthritis, and an old leg injury, I needed a new path.

 

My lifelong passion for bikes—both bicycles and motorcycles—led the way.

As my knee pain worsened, cycling—the activity I once loved—became nearly impossible.

That all changed during a visit to friends in Amsterdam, where we discovered their everyday mode of transport: the electric bike. One ride was all it took—I was hooked.

Unlike traditional cycling, e-bikes didn’t put strain on my knees, and for the first time in years, I could enjoy the freedom of riding again.

Guida, my wife, was just as inspired. Together, we realized how many people in the UK could benefit from this same experience.

With my background in engineering and her 30 years of customer service expertise, we set out on a mission: to make e-bikes accessible for everyone, while promoting fun, health, and sustainable transport.

After months of research and preparation, Top Dog Bikes was born.

What Our Customers Have To Say

  • Damien

    From start to finish and even afterwards this company’s customer service and aftercare is second to none. I ordered my Engwe Ep 2 Boost from Top Dog Bikes, Guida is a credit to this business and I never write reviews but the way she dealt with me from the first call to her after care email follow up should be commended. If you’re looking for your new e-bike or accessories this is the place to contact, you will be looked after, Thanks Guida and Top Dog Bikes. 5 ⭐️⭐️⭐️⭐️⭐️

  • Andy Blamires

    A Bike shop above and beyond

    This bike shop went above and beyond to help me out with an electric bike. Guida phoned me up and told me the bike i wanted was no longer been stocked and went out of her way to find me the same sort of specs for the the bike I wanted. A few hrs later she sent me an email with a bike that I was looking at before on a different website. She had sent me a email of the Vitilan electric bike I immediately said yes. About a week or so later my bike arrived I was so happy. So a big massive thank you to topdog bikes and especially Guida, hope to business with you again for my next bike.

  • Ben Clothier

    I looked at purchasing an Engwe E26…

    e-bike for some time and watched and read a lot of reviews before deciding.
    I then looked at prices and purchasing options and found Top Dog Bikes to be the best price. After talking to Guida Inman who was very helpful and walked me through various options I placed the order. The after sales from Topdogbikes and Guida in particular has proven my decision to be the correct one. So 10/10 to Topdogbikes.
