The motor power and data plug has been redesigned for dead simple removal and install: it is now one plug that plugs directly into the motor and can be unplugged by folding up a handle. Lastly, the motor now uses a cassette gear cluster, instead of a freewheel.
Hi Court, I discovered your site and it’s great. I’m 6’8″ tall, 274 lbs., and 71 years old and still biking but needing some help and assistance on long hills of pavement or crushed rock. Wouldn’t mind having a few coasting breaks too. And the step through appeal to me as I get older. Looking at ebikes and especially the Pedego step through Interceptor with magnesium wheels for weight carrying capacity. What do you think? Good choice or is there another out there that would fit this old boy?
The Cyclone system is the first electric bike motor kit to work with the bike’s rear deraileur to take full advantage of your bike’s gearing system. The kit can be installed on bikes with 6 to 8 speed rear cassettes. The result is a motorized bike with great low gear power and a comfortable high-end cruising speed.

An e-bike conforming to these conditions is considered to be a pedelec in the EU and is legally classed as a bicycle. The EN15194 standard is valid across the whole of the EU and has also been adopted by some non-EU European nations and also some jurisdictions outside of Europe (such as the state of Victoria in Australia).
Actually, the protected cells aren’t a great option for ebike packs. The protection circuit on every cell can overcomplicate things, not to mention that it usually isn’t rated to handle the same current the cell could without a protection circuit.
We are pleased to announce that ElectricRider is currently undergoing some major modifications. Many of the products ElectricRider has manufactured for years will soon be provided by a new company whom we’ve selected for their fresh perspective, strong morals and desire to serve the high performance LEV market.

Hi Jose, sorry to hear about dogs and strangers making you feel insecure on your bike :/ the most drag-free system I’ve reviewed so far is the Add-E because it doesn’t even touch your rear wheel when pedaling and it’s super light weight too. The only downside is that it’s not very powerful… It would still assist you well though and the 600 watt version can go over 20 mph if you pedal along and then keep you there more easily. The basic 250 watt system cuts out at 15.5 mph to comply with European laws but also costs less.
In the end, I opted for a DPDT+OFF rocker switch, as using diodes introduced forward voltage drop and this interfered with charging enough for me to have second thoughts. This arrangement does require that the BMS be “flashed” to initiate it, which can be done by the charger in charging mode but for discharging, http://electricbikebatterys.com found that shorting the B- and the P- for less than a second initiated the BMS and it then latched itself on, so I installed a reset button. If I had used a DPDT switch without an off position then I would not have needed to do this. However, when the BMS hits a low voltage group e.g. going up a steep hill, it will not automatically reset when the voltage recovers, so you need to use the reset button if you want to get the last bit out of the battery. I’m toying with latching this button when discharging, as the voltage drop knocks the controller out, so I think I’ll get a reaction like traction control, without having to manually reset the battery (which is annoying as it’s in a backpack).
1C charging is too high for most Li-ion. It’s too much to ask for right now, to be able to charge an entire pack in one hour. It can be done, but it’s not healthy for the cells. Aim for 0.5C at the most. I usually don’t go past 0.3C on charging.
The BMS I chose is a 30A maximum constant discharge BMS, which is more than I’ll need. It’s good to be conservative and over-spec your BMS if possible, so you aren’t running it near its limit. My BMS also has a balance feature that keeps all of my cells balanced on every charge. Not all BMS’s do this, though most do. Be wary of extremely cheap BMS’s because that’s when you’re likely to encounter a non-balancing BMS.
Lastly, there’s a small chance that it’s just a faulty BMS. This method is annoying, but if all else fails then you can try swapping out the BMS. More than likely though, the BMS is doing it’s job because one of the cutoff conditions is fulfilled and it’s just trying to protect the pack.

The main limitation of those holders is power – they can’t handle it. For a few amps, they might be fine, but ebikes require dozens of amps, which would surely melt those guys. Think about it this way: professional ebike batteries have big hunks of nickel plate welded between cells. The tiny little spring contacts of those holders will never compare to that kind of current carrying ability.
Excellent points Dan, thank you so much for chiming in… I was trying to keep the article approachable for newbies but also capture “everything” and I think it could get better with some work. I’ll take your suggestions and try to work them in 😉
Loved your comparisons as I’ve been thinking about an e-bike. I ride rurally with gravel roads and lots of long hills, some up to 3 miles and some steep. The plan was to take my cross bike and install a kit but not sure what brands are out and what type would work for my setup especially after watching your hill video. The other issue is durability and dealing with gravel dust. I’d hate to wreck and break something and would gravel dust ruin internal parts? Thanks!
PikeResearch, a for-profit market research firm, released a report in 2010 which included market analysis and forecasts for electric two-wheel vehicles. They concluded that, “The worldwide electric two-wheel vehicle market is expected to grow at a compound annual rate of 9% through 2016” and that “a lack of a well-defined retail channel hampers faster adoption in North America and Europe.” PikeResearch also forecasted that worldwide sales of e-bikes, e-motorcycles, and e-scooters will reach more than 466 million between 2010 and 2016, and China will continue to dominate the world market, with more than 95% of sales during this period. E-bikes sales are expected to have the largest share with 56% of the market.

I like the approach you’re taking, possibly a hardtail with hybrid or knobby tires… the suspension fork adding some comfort along with larger inner tube diameter. When you ride further and at higher average speeds, you tend to feel it in your back and neck more. For this reason, I have become a big fan of full suspension electric bikes… but you can approximate this with a hardtail frame and a seat post suspension. This setup is going to work with standard racks (that tend to stay put compared with beam racks or the Topeak seat stay Pack N’ Pedal rack).
hello. I have a KTM bike-trail’s 2013 model. I have problems with the battery. I had the bike wheel and I bought one original ktm 26V from the company. defect occurs so: I put the plug on the charger to charge the battery and flashing green LED lights and red and it is immediately interrupted – interrupted flashing red and the buzzer sounds and noises that can fix … ? Please help me if you know how. sorry for my English but I used google translator

The two most common types of hub motors used in electric bicycles are brushed and brushless. There are many possible types of electric motorized bicycles with several technologies available, varying in cost and complexity; direct-drive and geared motor units are both used. An electric power-assist system may be added to almost any pedal cycle using chain drive, belt drive, hub motors or friction drive. BLDC hub motors are a common modern design with the motor built into the wheel hub itself and the stator fixed solidly to the axle and the magnets attached to and rotating with the wheel. The bicycle wheel hub is the motor. The power levels of motors used are influenced by available legal categories and are often, but not always limited to under 750 watts.
