The Greenstar Bikes Ecoforce 1 is a single speed bamboo road bicycle with a reversible rear hub that easily converts it to a fixed-gear bicycle or "fixie".  This affordable bamboo bike is super light: the frame weighs less than 4 pounds thanks to bamboo and our recycled 6061 aluminum lugs.  The entire bamboo bicycle only weighs about 20 pounds.

The warranty on this bike is 10 years on the frame, single owner, for bikes purchased new and assembled by an authorized retailer.

Greenstar Bikes does not accept any bike returns.  They are more than happy to send you any replacement parts due to manufacturer's defect at no extra cost, but are unable to accept returns.

Top 4 Reasons Why Bamboo Is the Best!

  • Exceptional Properties - Strong as steel, light as aluminum, stiff like carbon yet more reliable, and naturally dampens vibrations.
  • Eco Friendly - No pesticides, no herbicides, no fertilizers. Ultra-fast growing and never killed (unlike trees) when harvested.
  • Socially Responsible - Low barriers to entry make this the perfect cash crop for emerging economies and small family farms.
  • Uniquely Beautiful - Yes it is. Extremely. The deep wood grains produce an iridescent effect. Like snowflakes, no two bikes are alike.

How Bamboo Compares To Other Materials:

  • Steel - Much lighter yet just as strong. Greater tensile strength.
  • Aluminum - Stronger yet just as light and more cost effective.
  • Carbon - Just as light and stiff, but no risk of catastrophic failure.
  • Bamboo- gives you the smoothest ride available due to its natural vibration dampening properties.

Bamboo Is Eco Friendly:

  • Fast Growing - Unlike trees, bamboo can grow up to 3 feet in a single day. Talk about watching the grass grow...And unlike trees, which can only be harvested every 10-15 years, bamboo can be harvested every year.
  • Clean Growing - Bamboo is incredibly hearty. It requires no pesticides, no herbicides, and no fertilizers. If you got dirt, water, and sun - you got bamboo.
  • Live Harvest - When it's time to harvest, you don't chop it down and kill it like a tree. You simply cut off what you need and the rest of the plant keeps growing. It's kind of like mowing your lawn.
  • Good for Soil - Bamboo is not a tree, it's a grass. It grows the same way your lawn does, by sending up shoots from its root network. This prevents soil erosion, reverses soil depletion, and benefits the entire ecosystem.
  • Good for Air - Bamboo is one of the best carbon dioxide absorbing plants in the world. All plants do it, but bamboo has multiple advantages, including its size and fast growth rate.

Bamboo Is Socially Responsible:

  • Bamboo Is Minimally SustainableAll you need is dirt, water, and sunlight. You don't even need pesticides, herbicides, or fertilizers.
  • No Complex Machinery RequiredOur iron bamboo is harvested by family farmers with simple knives. And there's no work to be done after the harvest: no plowing, no reseeding, no soil reclamation.
  • Bamboo Is the Ideal Cash Crop- With virtually no barriers to entry, no harmful emissions or byproducts, and no complicated infrastructure needs, bamboo is socially responsible.

Bamboo Is Uniquely Beautiful:

  • Visual ImpactThe rich depth of colors and naturally lustrous wood grain makes each Greenstar bike a fully functional unique work of art.
  • One Of A Kind- Just like snowflakes, no two bikes are exactly alike.  Each Greenstar bamboo bike is truly a prized possession.
