The Surface 604 Colt is a feature-complete hybrid city electric bike. It comes standard with a rear rack and integrated Spanninga rear light. The company has built a fairly large dealer network in both the US and Canada for test rides and warranty support. Offers responsive torque sensing pedal assist as well as trigger throttle override with full power, this can make it easier to get started or zip up a hill without clicking any buttons. The control pad and display are intuitive to use and great looking, good comfort with hybrid tires, a suspension for (with lockout and preload adjust), and a gel saddle. Responsive Tektro Auriga hydraulic disc brakes with large 180mm rotors and dual-piston calipers, upgraded Shimano Alivio groupset feels snappy and offers a large 11-34 tooth cassette range.
1. Powerful 500w Motor with 10.4 aH battery
• The Colt comes equipped with a 500W hub motor that is extremely powerful (peaks at 750W).
• With a torque sensor and throttle on demand, the Colt is great for those that could benefit from an extra boost to make it up the hill.
• Geared for performance - we paired all that power with an industry-leading 12mosfet 25A controller, so Colt delivers unmatched torque and speed.
• Watch out for other riders as you zip pass them.
2. Long-Range Battery Pack with Power Bank
• Colt's high capacity 48V/10.4Ah Samsung lithium-ion battery provides maximum range.
• Colt can handle heavy loads and travel up to 60 miles (97 km) on a single charge.
• As an added bonus the battery also features a USB plug for charging a mobile device on the go.
3. Whisper Smooth Torque Sensing Pedal Assist
• Precision torque sensing performance at 104 cadence pulses per revolution; 1,000 torque samples per second.
• Colt’s incredibly smooth torque sensor knows how hard you’re pedalling down to the microsecond and matches it with proportionate power.
• Custom drop out design delivers whisper smooth torque sensor sensation at any assist level.
• In fact, you’ll swear it’s as smooth as a mid-drive motor. Gone are the days of simple cadence sensors!
The Well Equipped Surface 604 Colt Commuter Hybrid Electric Bike is in great condition and ready for the open road and bike paths. I did a 21 miles bike ride with a full battery and still have 69% battery at the end of the bike ride. The bike is well equipped, fast, responsive, and very reliable. This bike comes with the original battery charger and key to lock/unlock the battery. I am asking for 950 or best offer.
