Monty 207 Kaizen

Dispatch time 1-2 days - this bike is assembled in our workshop before dispatch. Minor assembly required on arrival, details supplied with bike.

Super cool kids bike from the original BikeTrials brand, Monty.

  • Designed for riders from around 1.15m (3ft9) to 1.50m (4ft11).
- Featuring a completely new concept in trials frames, the long-standing 207 is back and better than ever!
- The latest Kaizen frame design from Monty was developed with their world class team, and is stiffer and stronger than ever whilst also being super light.
- This latest model combines the existing knowledge Monty have from making the best kids trials bikes on the market with new technology and unique looks to create the perfect bike for young trials stars of the future.
- Designed for riders from around 1.15m (3ft9) to 1.50m (4ft11), ages approximately 6 to 11.
- 20" wheels front and rear keep the bike agile and light weight.
- Soft compound light weight tyres improve grip.
- Relatively short stem keeps the bike to a manageable length.
- 16 tooth front freewheel and 14 tooth rear sprocket offers a gear ratio that is ideal for smaller riders with less power, while using the same style of setup that the 'big boys' use.
- Considerably lighter than other bikes aimed at the same age of rider.

This bike is supplied with a 6 month warranty covering manufacturing and materials defects. The warranty does not cover mistreatment or poor maintenance. Please ensure all the details on the warranty sheet supplied with the bike are adhered to. Certain circumstances (such as stripped threads or rounded crank arm tapers) only occur due to a lack of correct maintenance and all manufacturers are aware of these situations, so any claims due to incorrect maintenance procedures are much less likely to be successful.

We build this bike to a 100% complete state in our workshop before dispatch to ensure all items are manufactured correctly and nothing is missing, but we do have to remove some parts to ensure there is no damage during transit. You will need some basic tools (usually 4mm, 5mm, 6mm and 8mm allen keys and a 15mm spanner) for final assembly upon arrival. We have a video guide here to help, but please don't hesitate to contact us if you require any further assistance.

Please tell us which parts to change the brake of 207. I would like to use Magura HS 33 R Trial Bremse HS 33 for brakes. Please tell us the parts on the net shop. Best Ragerds. Mukai

Hi Mukai - To fit the HS33 brakes to your 207, you would need the Magura Evo2 Adaptor Kit. Unfortunately we don't stock this item separately, sorry. Thanks, Mark

If I change the stem would it be okey for an adult

Hi Sigge - thanks for your question. No, this bike is designed specifically for children, meaning the frame is smaller than an adults bike. Even with the biggest stem available, it would feel too small for a fully grown adult. Thanks, Flipp.

Hi Chris - thanks for your question. This bike is "designed for riders from around 1.15m (3ft9) to 1.50m (4ft11), ages approximately 6 to 11." You would be a bit big for this bike, and should be looking at full-sized alternatives for the best fit. Hope that helps. Thanks, Flipp.
