I went to Prague with my aunt. I am 48 and she is 70. As she wasn't used to ride more 'sporty' bikes, she was at the beginning a bit afraid. Eva was our guide and she managed very well to get her at ease. She was very helpful and friendly. It was a wonderful ride along the river. The places for the coffee break (with cake :-)) and the lunch were very nice, the food was good. We got back with the train and took a little ferry. We ended the day with a drink on a boat, a very nice place and not so touristic. The pictures will tell you a lot.

David was a brilliant tour leader! He was very knowledgable about the city's history, culture, and people, while also entertaining us with personal stories and providing a different perspective on Prague. He took great care of us (I got a flat tire and he took my bike and ran with it while I had his bike so as not to interrupt the tour) and even extended the tour by 2 hours so we could sit in a beer garden and see a couple extra sights! What a fantastic way to spend the day, Highly recommend!!

My husband and I had not ridden a bike in 10 years but we decided to take the bike tour to Karlstejn castle. Martin, our guide, set a pace which was easy to follow and ensured that we knew how to operate the bikes. A 16 mile ride, mostly flat with one part that is half-way up hill. No shame in walking that part and Martin made sure that no one was left behind. One has options to take a final uphill ride for a great view of the castle or continue on to the castle via a flat road. We chose the uphill and it is steep toward the end, but we made it walking. The view is worth it.

Mid-way there is a break for coffee and pastry and the tour concludes with a nice lunch (including a glass of beer or wine if you chose). We had a small group and just enjoyed the scenery and company.

Helpful Information:
Tour duration: about five-six hours. You can visit the castle if you wish. We passed as a bit OD'd on castles but it looked interesting.
Tour includes: hotel pick-up, transportation to the bikes, helmet, lunch, and train ticket back to Prague (about 35-40 minutes). Bring a bottle of water for yourself when riding.
Bike Experience/fitness: You don't forget to ride a bike. If you prefer a leisurely ride, no problem. My husband and I are in reasonable shape, walk daily, and hike. We had no problems. Check with Martin about young children and if you have health issues.
Fellow riders: We had a great group- various biking levels of experience but no problems.
Booking: In the summer and fall, I would book ahead as the tour fills up.

I give the day an A+. Thank you Martin.

Biko Adventures was one of the highlights of our Prague trip. I (in my late 20s) traveled to Prague with my parents (in their early 60s) and convinced them to do a 35 kilometer bike tour from Prague to Karlstejn Castle. Neither had been on a bike outdoors in over 15 years. I researched the different tour options available through Biko and found many options I'd be interested in, but the Karlstejn trip turned out to be the best tour for my parents as beginner riders (though a few narrow passages to navigate over bridges). Petar was our guide, and we rode along with two other couples, which was a nice-sized group. It was really great to bike through the countryside, outside of Prague, along the river and end at a beautiful and historic castle which we had to to explore. We finished off with a Czech beer and traditional meal in the town of Karlstejn. I truly recommend Biko in general, as the staff and guides were very friendly and they have a quaint little shop in Prague (which we bought graphic t-shirts from Filippo, the owner), and I especially recommend the Karlstejn tour for travelers looking for a bit of adventure, but on the more leisure side. I would definitely come back to ride with Biko!

We decided we needed some exercise after all the great food and beer and so we joined Martin for a Karlstejn Castle Scenic Bike Tour that our Airbnb host recommended us. What a great idea! We had an awesome day with our guide Martin touring the outskirts of Prague. The ride followed rivers most of the time so it was not just not too difficult but mainly beautiful. The best part was the last part when we arrived at an outstanding spot where the Karlstejn Castle was suddenly below us and we could see nothing but the castle and forrests all around. Finally the lunch and beer in Martin’s favourite restaurant in the village below the castle was the last piece of a mosaic to make it an unforgottable experience and the best part of our holiday in Czech. Would definately recomment Martin and his agency and we look forward to join him on canoe trip the next time we visit Prague.

When looking for a cycling tour of the Czech countryside I picked Martin's company because I hoped that a new, niche operator would provide a more personal experience than the larger operators that cater to big numbers every day.
Despite some difficulties with my schedule Martin made a special effort to make sure I got the tour I wanted.
Martin has a big passion for showing others the outdoors, away from the crowds.
I had a great day being guided around beautiful countryside, rivers and villages on a brand new bike, taking in the sights and atmosphere. Lunch and beer was welcome and tasty but for me the real delight was in cruising along quiet roads in beautiful nature having a laugh as we went.
Highly recommended

This was such a wonderful day. Gorgeous and interesting scenery. Wonderful lunch spot just outside Karlstejn. We really wanted to get out and experience life off the tourist trail and this was a great way to do that. Equipment was very nice. We are not any kind of serious cyclists at all (I ride my bike casually around husband rides mayne once a year. HA! so it was a little bit of a challenge for us, but worth the effort! The walk up to the castle was probably the hardest part though, in reality. But the payoff was breathtaking. Lukas was great company and very patient with us. Unforgettable and a great sense of accomplishment :) Thanks Lukas!

Lucie was a great guide, and the bikes were in great condition. The route was fairly easy, and the one fairly brief challenging climb was totally optional. Along the way, it was great to see a little slice of life along the river, poppy fields, and even in late July there were a respectable concentration of wild flowers.

(The one section was "challenging" in the context of a low-key tourist route that's predominantly breezing along paved flats by the river. There is one climb and one downhill, but the route is designed to burn off a morning pastry, and develop a proper thirst for a great beer at the end, not to test your mettle.)

Martin is a nice guy and the whole trip was really enjoyable. We were picked up from the hotel on time. Me and my friends were joined by 2 pairs of nice couples. The bikes were good except the seats were a little bit too firm so make sure you were a nice pair of pants. The ride was long so some demand for physical endurance.
The highlight was the lunch with good environment and good local beer. Entry to the caste was only by paid tour so we ended up not having a chance to peep inside. After riding a bike for the whole morning we did not really like to walk another hour.
Overall good trip, good guide, good ride, and good beer.

This is the perfect trip for a day in the country outside Prague! Martin is an excellent guide. His bikes are top notch and in excellent condition. He is patient and adjusts to the strengths of his group. The ride is not difficult or too long. The scenery is beautiful along the river and through little villages. He makes time for a pastry and coffee stop - yummy. Riding into Karlstejn was so interesting. After a good lunch and cold beers, you have a time to visit the castle. Martin then provides train tickets back. A real plus on a hot day. I cannot think of a better way to spend a summer day in Prague.

This experience is the best!! I had a fantastic time with Lukás. We biked for a total of about 38 km, and the whole time the views were incredible and the insights that Lukás provided along the way were fascinating. We stopped for tea and coffee about halfway to the castle, and for lunch in this small village where I had the best Czech food of my entire trip to Prague. The castle itself was beautiful, and the view of the valley from it was even more so. Luke's was so friendly and knowledgeable and I couldn't have asked for a better way to see the countryside surrounding Prague!

First of all, these bikes are AWESOME. It's like having the power of a scooter while still pedaling -- very welcome on all of the hills. Jan was a great tour guide, a gracious host, and the pride he feels for his city shone through on his tour. We would never have seen the majority of the sights that we stopped at with Jan and having his insider local knowledge was priceless. We were a bit hesitant because of the weather (and it was cold!), but this was our favorite activity on our ten day trip!

We took the bike trip with Martin from Prague to Karlstejn castle. The bike ride was not difficult, though it was our first time riding a mountain bike.
The trip went along the river through small lovely villages and we even got the chance to swim in the river nearby.
After the bike ride we enjoyed local cuisine and cold beer and wandered around the Karlstejn castle.

We recomment the trip to everybody who wish to escape the city for one day.

Thank you for an excellent day, Martin!

Lukas was a great host for this experience, very friendly and knowledgeable! It is about a 30km bike ride with a nice coffee break and lunch along the way. Perfect amount of rest to break up the long ride, which is for the most part flat. The castle is off the beaten path of the crowds of tourists, so it's nice to see a part of Czech you otherwise wouldn't see if you just toured around Prague.

Anna arrived on time in a nice vehicle with great bikes. We had a quick ride to the parking lot to begin our trip. The ride was perfect, nice views, nice trail and a great host. The ride up the final hill, or in my case the walk up the final hill was worth it to round the corner and see the view. I would recommend this trip, this company and Anna as a guide.

We took the View Point Ride on our first full day in Prague. It was a fantastic way to see the major sites, get orientated in the city and learn some history. Cannot say enough about how knowledgable, personable and fun our guide Kate was. We walked away with a great feeling for the city and the people. We would highly recommend this company.

We had an amazing time doing the trip from Prague to Karlsejn by bike. We saw the suburbs in Prague, we traveled through flower fields, bridges and narrow paths through little forests. Everything was great, it was a highlight in our trip to Prague. I definitely recommend doing this if you travel in Prague and the weather is nice and warm.

This was a really nice ride, even in the mist. Petr, our guide, was informative, fun and considerate of our 77 year old pace. We were very impressed that Fillipo was careful about the weather and wouldn't let us go on a day when it was expected to rain a lot. We'd highly recommend Biko!

Definitely one of the highlights of my trip. The bikes provided were great, I forget their brand but they were definitely top notch, the guide was also really nice.

The pace was leisurely but can be as fast as you want. We wanted to go a little slower and take in the scenery.

A great way to see highlights in Prague while on an electric bike! Beautiful countryside, important sites and a lot of fresh air. Peter was a delightful guide: enthusiastic, knowledgeable, friendly and spoke English very well.
