Bests & Worsts Reviews from Amazon

I am extreamly happy with this kit. It really does all it says and performs better than I expected. Took about 3 days to fit this to my doner bike. ( Walmart, 26”, Bay Side cruiser ) It took 3 days, after work, because I was very careful and I made some home made TORQUE arms. Basically, I used a 10 mm open ended wrench from a hardware store, and using a propane torch, bent it to fit snuggly against the bike frame when locked onto the flats of the wheel shaft just outside of the wheel nuts. I was worried that the bike frame might twist out, so I made these torque arms. Most e-bike shops recommend torque arms. The spokes are very thick and the rim is double walled so the wheel is very strong. I have been ridding it for 2 months and have rode 200+ miles. My top speed has been 32 mph on level ground and 42.1 mph going down hill in my housing development. ( too fast! ) It will accelerate to 32mph quickly. I really like the twist grip throttle and the display is large and easy to read. For batteries, I ordered Qty 2, 7-cell, 5,000mah LiPoly batteries from HobbyKing. ( ZIPPY Compact 5,000mAh 7S 25C Lipo Pack -Single Balance Tab Version) $56 each. Total battery cost =$110 + shipping. ( http://www.hobbyking.com/hobbyking/store__85857__ZIPPY_Compact_5000mAh_7S_25C_Lipo_Pack_Single_Balance_Tab_Version_.html ) I fly electric airplanes, so I have the chargers to intelligently charge Lipoly batteries. I connect them in series, making a 14cell, 58vdc, 5,000mah battery pack. I'm putting around 58 volts to the motor on fresh batteries. ( 4.2vdc per cell x 14 cells = 58vdc ) So far, after 10-12 rides, no issues with that 58vdc to the controller. I bought a Watt meter from Ebay and installed it next to the LCD meter. ( Digital LCD Watt Meter Battery Voltage Current Power Analyzer Tester 60V/100A RC ). This allows me to monitor the battery voltage, watts used and mah used as I ride. ( I’m a nerd ) My Watt meter says, when I floor it, Im using about 1250 watts!! I run the batteries from 58vdc down to around 52vdc. This leaves each Lipoly cell at around 3.7vdc. I know I can run them down lower, but Im being careful with my batteries. With these 5000mah batteries, I estimate I can go approx 11 miles. ( 5.5miles out and 5.5 miles back ) Guess this really depends on much I want to pedal! LOL. Generally, I put bike in PAS mode 2 and the bike in 7th gear. This way I cruise around at around 16 -18mph, using around 8-12amps If I want to go faster, I just use the twist throttle and goose it! ( 28amps ) Speeds above 25 or 26mph get kinda scary on these local neighborhood streets. On the country blacktop roads, I let it out and cruise at about 30-34mph. I put the batteries in a Bell brand, rear saddle bag that fits under the seat. Very compact and neat. The controller is mounted, vertically, on the seat post, just above the chain guard. All wires, etc, are crammed into a small compact camera bag, tied to the seat post, above the controller. You would not know this is an electric bike if you didn’t look at it closely. The motor is strong enough to get me going (240lbs) from a dead start and most inclines are not a problem. Steep hills require that I peddle some to keep speed steady but not too much. This also will extend battery life. If I buy 2 more 7-cell, 5,000mah LiPoly batteries from HobbyKing, I calculate that the 10,000mah battery pack will get me 20-25 miles as long as speed is kept around 15 mph. This motor pulls twice as much current at 20 mph than it does at 15 mph, so slower really extends battery life. Issues I had.... 1) .. I wasn't able to use the front disk brakes that came with the kit. ( my doner bike couldnt use them ). 2) .. The PAS sensor and magnet assembly would not fit my peddle/bearing assembly. I ended up mounting the sensor on the outside of the magnet wheel. Guess it doesn’t matter as it works perfectly. 3) ... Also, my rear derailleur will no longer reach to 1 st gear. The cassette is just too far away from the derailleur and it hits the motor hub if I try to have it go into first. So I’m restricted to 2nd through 7th even with re-adjusting the derailleur. Not a real issue for me, as I generally leave the bike in high gear all the time anyway. :) Make sure your bicycle is in top condition before putting on this E-bike kit. It pays to have new tires, inner tubes, brakes, etc. The kit with my 5,000mah lipoly batteries, add about 30 lbs or so to the bike. Total cost of this new, e-bike was around $470. ( $100 bike, $120 batteries, $250 kit ). This has been a fun build. Im 62years old and I enjoy cruising around the park and neighborhood on weekends. Questions? surf@imonmail.com
