High performance cycle model 2500 watt 52 volt system geared electric bike kit complete. In excellent condition only used 300 miles. Has 9 gear sprocket and a geared drive which is much faster, lighter than electro static free wheel in which the hub is much larger and much much heavier not to mention slower. This is a very very fast wheel I weigh 250 lbs and clocked my Catrike at 41 mph. Yes it is a perfect fit for Catrike 700 models  The battery is a 52 volt 15 amp-hour Deep cycle lithium battery. These take a big leap ahead of LifePo4 batteries by offering the newest Tri-metal technology LiNiMn02. Rated for a steady 35 amps constant and 52 amps burst rate. ---Weighs just 13 lbs. ! On Busettii bikes its then regulated down to 27 or 30 amps to keep it running cool and efficient even on big slopes. Uses high speed chargers or normal. Most other Lithium batteries are not Deep cycle which means they can only use 60--75% of the stored charge. Deep cycle means they can actually use 85--95% of the stored charge as output for your motor. Deep cycle lithium (LiNiMn02) has better RANGE, SPEED, DURABILITY AND CHARGES UP TO 50% FASTER. ------- This battery comes with a free High speed smart charger that uses hard wired cell balancing. This battery is also hard wired to each cell for the ultimate in cell balancing that increases power flow and long range performance ! I chose this battery because it has a locking rack and is the best on the market much better than HPC batteries.   I could ride up to 50 miles on a charge at 18mph. Tire is like new and tube just newly replaced . Has Cruze control digital computer which tell you speed, distance,battery life peddle assist effort and much more. Hand throttle and locking battery rack for rear mount. Recharges in about 4 hours from rundown state. Faster if not run down. Green light tells you full charge.
