Bike Information

For those who are experienced riders, you probably already know what you're looking for. On the other hand, for those who still are not sure which BULLS is your ideal bike, here is a simple process to find out:

1. What are you going to use the bike for and where?

Mountain Bike (MTB)

Mountain bikes are typically ridden on mountain trails, fire roads, logging roads, and other unpaved environments. These types of terrain commonly include rocks, washouts, ruts, loose sand, loose gravel, roots, and steep grades (both inclines and declines). Mountain bikes are built to handle this terrain and the obstacles that are found in it like logs, vertical drop offs, and smaller boulders. There are two type of mountain bikes: Hardtail, which do not have a rear suspension; and full-suspension ones, which have front and rear suspensions.

MTB hardtail

Hardtail bikes transfer pedaling power to the rear wheel more efficiently than Full suspension models. On non-technical surfaces, this results in better acceleration and makes it easier to sustain higher speeds over a long time.

If you're just starting out, on a really tight budget, or just enjoy simplicity, you should definitely consider a hardtail.

MTB Full suspension

On bumpy, technical downhill trails, FS bikes have a clear advantage. Rear suspension allows more of the available rear wheel to actually reach the ground by allowing the wheel to better articulate over obstacles.


Yes, all bikes can ride on roads. However, a road bike is one that's optimized for riding on smooth pavement. It usually has skinny tires and are built for traveling at speed on paved roads


Go for a hybrid if you want to get some of the best bits of mountain and road bikes all in one package. With an upright, comfortable and stable riding position, hybrids also give an efficient experience on roads.


Designed with city streets in mind, urban bikes are rugged and sturdy with tough frames and strong wheels. They are the obvious choice for urban commuters


It is really easy. All you need is a few simple measurements of your body and input the data into our BULLS size calculator which shows up when you click bicycle model under the "What is my frame size" link.

Every BULLS is 99% pre-assembled in a way that is very easy to complete the final assembly by following a few very easy steps. All tools are provided when you order your BULLS bike (except for the torque hex wrench, which in case you do not have one already, you can buy it in our website) and assembling should not require more than 20 minutes

That depends on the type and model of bike you want. All the specs of all BULLS models, including the weight, are described under the tab "DETAILS" in every bicycle model.

At BULLS, we believe that selling online lets us reach our customers in a much better way than through a retailer. It also allows us to give you the best possible price for your bike since there are no middleman between you and us. So for the United States, you can only buy BULLS through our website.

All of our bikes are designed and tested by us in our German headquarters in Koln. Once we have them approved and certified by international standards, we manufacture the bicycles in South East Asia under our own staff supervision.

Yes. Our Blem Bikes can be purchased through a third party dealer. Demo bikes have experienced light to moderate use by the media, thus warranties on demo bikes are void.

Technical Information

We keep the rear derailleur for all BULLS models sold in the United States. Just go to "GEAR" section in the website and you will find it ready to order under "DERAILLEUR HANGER".

Your BULLS arrives to its destination 99% assembled and fully calibrated. That means, only a few simple steps would be necessary to have your bicycle ready to be ridden. We will ship with your bike very easy to follow assembly instructions and all tools necessary for assembling that 1% left.

These are five easy steps you should perform before every ride. These will help you prevent major problems from occurring:

1. Inspect the tires: Road tires typically require 80 to 130 psi, mountain tires 30 to 50 psi and hybrid tires 50 to 70 psi. To find your ideal pressure, start in the middle of these ranges, and then factor in your body weight. The more you weigh, the higher your pressure needs to be applied. For example, if a 165-pound rider uses 100 psi on his road bike, a 200-pound rider should run closer to 120 psi, and a 130-pound rider could get away with 80 psi. Never go above or below the manufacturer's recommended pressures.

2. Test the brakes: Spin the wheels and apply the front and rear brakes independently of each other. Check that the brakes engage before the brake lever reaches the handlebars and that there is enough stopping power to be safe. It is also important to ensure the brake pads are not worn.

3. Lube the chain: Make sure your chain is lubricated. If not, apply a small amount of lubricant to the inside of the chain as you pedal backward so the entire chain gets an even coat.

4. Check the shifting: Check that the rear derailleur shifts evenly and smoothly between all the gears on the cassette.

5. Check the wheels: Make sure the quick-release skewers are tightened correctly.

Most bicycles come with Wellgo pedals. However, high-end models come with no pedals. All information on each BULLS is in the website under each model.

Almost all mountain bikes are equipped with front suspension. Suspension on mountain bikes offers a range of adjustments to fine-tune the riding experience. Variations include the type, amount of travel, robustness and method of bump absorption. We recommend you keep your suspension clean from dirt and service it as the manufacturer recommends.

Rear suspension is only found on full-suspension mountain bikes, and is commonly referred to as the rear shock, or "shock" for short. The shock allows the rear wheel to soak up impacts, helping to keep the tire in contact with the ground, increasing rider control and decreasing rider fatigue. We recommend you keep your suspension clean from dirt and service it as the manufacturer recommends.

Road tires typically require 80 to 130 psi, mountain tires 30 to 50 psi and hybrid tires 50 to 70 psi. To find your ideal pressure, start in the middle of these ranges, then factor in your body weight. The more you weigh, the higher your pressure needs to be. For example, if a 165-pound rider uses 100 psi on his road bike, a 200-pound rider should run closer to 120 psi, and a 130-pound rider could get away with 80 psi. Never go above or below the manufacturer's recommended pressure.

This is a matter of taste. However, 26's have lost popularity in the past years and we expect this to continue in the near future.

We will ship together with your bicycle a two-set of tools that you will need to assemble your BULLS: A BULLS Hex Multi-tool and a BULLS 15mm Pedal Wrench. For carbon models, you must use a torque wrench. If you do not have one, we encourage you to get one in our website under the "TOOLS" category.

Generally speaking, this is a great way to transport your BULLS. Make sure you have enough space so your BULLS does not suffer any unnecessary stress. If you detach your front wheel, make sure you do not pull your brake lever, as this will clamp your break pads.

We do not recommend you transport your BULLS using a roof rack. The force of the wind will cause stress to those areas where your BULLS is clamped. Generally, those places are not designed to withstand the extra force.

This is a great way to transport your BULLS. Be careful when you mount your BULLS onto the rack since this could cause damage to the paint and/or decals.

Whether you're travelling or sending your BULLS in for service, the BULLS BIKEBOX is hard enough for safe transportation and can be used several times. You will need to use all the packing material that came with your BULLS.

  1. Unthread and remove the pedals.
  2. Open the front quick release and remove the front wheel.
  3. Insert the plastic bleed block between the brake pads (only for disc brake models).
  4. Insert the plastic brake rotor protective caps onto both sides of the axle. Attach the protective carton to the front wheel.
  5. Insert the front wheel spokes onto the right crank arm (make sure you do not damage any of the spokes when doing so). Tie the wheel to the frame down using a string.
  6. Now wrap the protective foam around the chain stays and secure it with tape.
  7. WARNING: Do not wrap the chain with tape. Do not attempt to release the tension on the chain at all.
  8. Remove the seat post with the saddle all together. If it is a quick release, simply open the quick release to open the seat post collar. If it is a hex tool just turn it counterclockwise to open the seat post collar.
  9. Now remove the handlebar. To do this, remove the bolts of the stem face plate using your BULLS multi tool by turning them counterclockwise.
  10. Now that you have removed the handlebars, install the stem face plate back so it doesn't fall off and get lost.
  11. The handlebar should be free. Wrap the handlebar in bubble wrap and secure it with tape. Turn the fork backwards and attach the handlebars to the drive side of the bike with a rubber band.
  12. WARNING: Be very careful when handling the handlebar. You do not want to twist and pull on the cables and housings or brake lines.
  13. Finish putting all the protective packing material on the frame to make sure nothing gets scratched along the way.
  14. Now place the bike in the BULLS BIKEBOX. Start by carefully inserting the rear wheel of the bike then the front fork. Make sure you do not bend any of the brake rotors or derailleurs in this process.
  15. Place all the accessories (front wheel quick release skewer) in the small parts box along with your proof of purchase and RA form if it is a warranty claim. Seal it with tape and place it next the rear wheel in the box.
  16. Put packing material on the seat post and saddle so they don't scratch anything and place it by the rear wheel.
  17. Close the box flaps and secure the box with tape.
