The Greenstar Bikes EcoCross Hybrid is a multi-purpose 21 Speed bamboo bicycle.  Perfect for streets, trails and off-roading, the EcoCross will help you ride up hills seamlessly and enjoy your ride on almost any terrain.

Best of all, the EcoCross Hybrid is affordable and still has all the beauty, quality, and top-notch performance of a bamboo bicycle.

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, lightweight as aluminum, stiff like carbon yet more reliable, and naturally dampens vibrations.
  • Eco Friendly - No pesticides, no herbicides, no fertilizers. Bamboo grows fast and is 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 - 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.

We work very hard to ensure we offer the LOWEST PRICES ONLINE. 

We want you to feel confident you are getting the lowest price for your product compared to any other online store, and we will match their lowest price accordingly.


The price you see is what you get. 

We don't add shipping costs, sales taxes, oversized charges, or anything else. 

Some companies advertise a much lower price, then sneakily add charges further in the checkout process.  We never do that.


  •  It does not apply to prices for our own store bought at different dates.   We reserve the right to change prices due to fluctuating sale prices from our manufacturers.  Once purchased, you "lock" in that sale price.  If price for that same item in our store decreases tomorrow or at any future date, you will still be locked into your original sale price.
  • Promotions such as rebates and buy one, get one free offers are not eligible.
  • The product must be in stock on the competitor website.
  • The competitor must be an online store (it cannot be a physical retail store) and it cannot be the manufacturer's own online store.
  • The website cannot be a discounter or auction website (eg eBay, Overstock, etc)
  • The competitor must be an Authorized Dealer for the product in question.
  • The product has to be genuine and cannot be a knock-off sold at a much lower price.
  • The Price Match Guarantee is for the final price after shipping and sales taxes.  Some online stores advertise a lower price but add on shipping charges and sales taxes in the checkout process, ultimately making their price higher than ours.  We never have hidden fees.
  • If you purchase something from us and subsequently ask for a price match from another store, it has to be done within 5 days after purchase date.
