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!
craig it should not damage your controller. When you connect two batteries together in parallel it will actually extend the life of both batteries because you are not taking as much of a toll on them when discharging and hopefully not running them down as low.
I finally made it happen on BMS #3 (the unfortunate thing about AliExpress is that every dumb mistake that kills a part is another month added to the project) and the battery seems to work great, though it only has a couple miles so far.
The nickel is surprisingly soft, which means you can use an ordinary pair of scissors to cut it. Try not to bend it too much though, as you want it to remain as flat as possible. If you do bend the corners with the scissors, you can easily bend them back down with your finger.
Next comes the heat shrink tube. Large diameter heat shrink tube is hard to find, and I got lucky with a big score of different sizes from a Chinese vendor before his supply dried up. Your best bet is to check sites like eBay for short lengths of heat shrink in the size you need.
Great article. As the average ebike shopper does a lot of product research, this explains really well the differences and benefits of the three major drive set ups..none are perfect in all situations. I need all three in my garage. Direct drive rear hub for my high speed 30 mph+ ebike. No gears to melt down. Mid drive for my mountain goat super climber and my real favorite and most used, the internally geared rear hub (not a big fan of front) for everyday riding. The free wheel aspect while coasting or in torque sensing pedal assist makes for a much more enjoyable ride. Keep the review pedal to the metal Court!
very steep hills. The only two drawbacks of a geared motor is a higher possibility of wear due to more moving parts, and a higher noise level than a direct drive motor. But we believe the benefits far outweigh the drawbacks and make the BH Neo bikes a highly compelling option.
If you have time, batteries for electric scooters canada be curious to hear about the pros and cons of this kind of approach. Is the main drawback simply the cumulative size of the plastic housing? Or is there some other limitation to this kind of hardware that makes it unsuitable?
Wow. Thanks for the info. Do you mind if I ask more? How fast does the ST2 go? Does focus thron impulse (FTI) have the same torque as the ST2. The video mad e the ST2 look very good. what do I get from FTI that I don’t get from ST2 other than suspension? Is there a price delta? I have not looked at the other bikes you mention. Can you web site to a comparison of them all? I really want to buy before summer. Thank you so much for the info. craig
My daily driver ebike has 8 cells paralled (14s8p) and it’s been working great for a long time. You can certainly make two 13s4p packs and parallel them after the fact, but don’t be afraid of making a single pack. As long as you use good quality cells, the risk of a parallel group dying is incredibly small.

I’m sorry but I’m not certain. Here in Israel we are on 50hz so I haven’t tried that model on 60hz. I do however have some friends in the US that have that model on 60hz. They have been happy with it, but I haven’t used it myself so I can’t say how it compares to my experience.
thanks for detail explanation , I was enjoj reading it. Well, I am interesting why did you pick this tipe of battery, I was thinking to use LiFePO4, I know there are usualy 3.2V it is less than 3.6V like here? Also, can you explain me how to calculate max current of battery, it says that you get 8.7Ah, but how much Ampers and what is the power of battery, how many Watts (P = U * I)? Furthermore, without welding, can I do on contact connection, like for example are battery in remote control?
Glad to help! It’s an interesting time for ebikes because some states and cities place restrictions but the national law is < 20 mph unassisted and < 750 watt motor = bicycle. I've been to towns where citizens have challenged the local rules and won... and the rules are rarely enforced for people who are riding responsibly.

I have test ridden many and narrowed my favorites to the eMotion City Wave and the Pedego City Commuter, with 28″ wheels. I don’t anticipate lengthy trips – likely up to 30-40 miles tops, however we live in the hills of NH, so I would be using pedal assist and/or throttle for the tougher climbs. While I love the City Wave ride, I worry a bit about the 350W vs. the possible 500W on the Pedego. I am 5’8″ and weigh 138 lbs. Your thoughts? The second big change is that the motor now runs at 48V, making the motor both accelerate and regenerate much more efficiently and powerfully. Finally, the fit and finish of the Syno-Drive has been considered from the perspective of service. Instead of a bolt-on axle, the Syno-Drive uses a modern thru-axle for added rigidity and easy removal. I then took my second sense wire (or your third sense wire if you have one more sense wires than parallel groups) and soldered it to the positive terminal of the second parallel group. Again, note that I’m soldering this wire to the nickel in between cells to avoid heating any cell directly. Continue down the row of cells placing a weld on each cell. Then go back and do another set of welds on each cell. I like to do 2-3 welds (4-6 weld points) per cell. Any less and the weld isn’t as secure; any more and you’re just unnecessarily heating the cell. More and more welds won’t increase the current carrying ability of the nickel strip very much. The actual weld point isn’t the only place where current flows from the cell to the strip. A flat piece of nickel will be touching the whole surface of the cell cap, not just at the points of the weld. So 6 weld points is plenty to ensure good contact and connection. I guess I’ll just have to risk some deterioration on the cells. I don’t think there’s much of an effect, as I did it on an old 18650 cell to test. The joint and surrounding areas were cool to the touch within 1-2s of removing the heat. I don’t know what you mean by saying your battery is 36W, batteries can’t be measured in watts. The only way to know what power your bike needs is to multiply battery voltage by controller current. If you can’t find a marking on your controller that says what its peak current is, you’d have to measure it with an ammeter, like a clamp on DC ammeter that can measure around the battery wire. 10.

I highly recommend using a BMS in both Li-ion and LiFePO4 batteries. As a Li-ion vs LiFePO4 question, one isn’t necessarily better than the other. Li-ion will be cheaper and probably more powerful, but LiFePO4 is going to last years longer, so it’s all about what you want in your battery. Hi Len, I think I understand and was recommending against the added weight and complexity of two motors. It has been done (Easy Motion sells a couple of all-wheel-drive ebikes) but wiring both motors into a single battery could be tricky and the alternative of having two batteries would take up a lot of space and add weight. In terms of torque from mid-drive vs. rear hub, I think it depends on the system you go with, both can be powerful and effective… You made a good point about the chain and rust. I don’t have enough data to recommend one way over the other, both have pros and cons… I might go with the cheaper option since it sounds like the bike is going to get run down in the environment so replacement will be less expensive down the road. Hey Brian, good question. You can actually do regenerative braking this way, the only problem is that you won’t be using the balancing circuit part of the BMS as it will charge straight back through the discharge circuit. Theoretically this is fine, with the exception of one specific case where this could be a problem. If you charged your battery at the top of a huge hill and then immediately rolled down that hill for a long time while using regenerative braking, you could actually overcharge the battery. That scenario is pretty rare though. I’ve reviewed all of the bikes you mentioned including those from Pedego (which also makes one of the Ford Ebikes), Specialized and Flux. I disagree with your local bike shop about Pedego being low quality… some of the models are a bit basic and “classic” in terms of design but the company provides good support and honors their warranty, they even did a voluntary battery recall a year or so back which was proactive and upstanding. The downside there is going to be higher price and finding a local dealer. [redirect url='http://electricbicycletechnologies.com/bump' sec='7']
