This bike only needs to get me to and from work on paved roads (and some sidewalks) and I don’t plan to ever take it on any trails but it does need to be able to handle hills. I have a local bike shop near me, but they currently don’t sell anything electric (the guy did warn me against Pedego bikes, though…saying they were not good quality. I mention that to say this: I don’t know how good any local service options are going to be for me, so simplicity and having a bike that works are important. Also, I’m on disability and don’t have much money, so price is a factor (that’s why the Flux on Indiegogo appeals to me).

A trail-worthy speed pedelec with premium accessories like aluminum fenders, integrated Supernova lights, a removable color LCD display, and regenerative braking. Very well balanced, especially for a hub-motor electric bike, the air fork, hollow-spindle bottom bracket,……

This is what I refer to “small cells”, the 18650 (cordless tool) type cells which need to be spot-welded or soldered together to form a large pack. The big advantage of these cells is they offer better cooling because of the nature of their shape to the LiPo soft pouches, and therefore have the capacity to last longer.

Hi Joseph! Sorry for the confusion… I realize it can be overwhelming when you really dig down. Two things come to mind for you regarding a good mid-drive system available after-market and the internal shifting question.

I want to build a 36v ebike battery for my 36v 500w motor. What battery you recommend for me which gives the enough current and capacity. My plane is to build a battery with 40 cells 10 in s and 4 in p,

One of the only full suspension electric cargo bikes I’ve tested, the suspension is adjustable and provides a lot of comfort to you and your cargo when paired with the premium Schwalbe tires. Excellent safety features including integrated LED lights, the headlight points where you steer and has……

The most noteworthy battery supplier is based in the USA and is offering lithium packs based on high quality cells.  A new vendor in 2015 is Lunacycle.com , so…check them out for a multitude of different packs at a very reasonable price.

Alec wants your wheels to be strong and true when they leave our doors, and a well-built wheel will stay that way for years.  Alec would rather be outdoors, but he comes in to E-BikeKit each day to make sure that you’ve got what you need to make your own outdoor adventures happen. A day when Alec can keep you rolling down the road and enjoying your bike is a…

It’s a good question. You need to use a 5s BMS. You can’t use a BMS rated for more cells because if the BMS see’s that cells are “missing” it will likely trip the protection circuit and your battery won’t provide batteries for e bike current. I’m not sure how easy a 5s BMS will be to find. A quick Aliexpress search shows me that something like this will probably work.

Any electric bicycle could use any of these sensor types (or multiple sensors like throttle and cadence sensing assist) but Class 1 only allows for assist while Class 2 allows for throttle and assist. So it’s not a matter of linking motors with sensors and input types (even though some motors only work with specific sensors) it’s a matter of how the manufacturer built the bike and which control systems they chose. All Bosch driven bikes use a combination of cadence, wheel motor and torque… Some BionX use a trigger throttle and a torque sensor. Hope this helps

It’s not impossible, but I don’t have high hopes. When a few cells die like that, they tend to kill the other cells in the same parallel group and often can kill cells in the series groups adjacent to them. You could be looking at replacing a large number of cells outside of the ones with obvious damage, and it will be hard to confirm that you’ve found all the dead cells without pulling apart most of the pack. If you’d like to try, there’s a chance you can end up saving the pack for less than the cost of replacing it, but it’s going to be an uphill battle.

You don’t know Ecospeed. If you did, and if you tested, you would realize that Ecospeed should be rated as the number one mid drive system out there. Based on years in business, satisfied customers, technology, engineering, and service. I know, since I have had Ecospeed for 5 years or more and I have two of the latest iterations of Ecospeed (one mtn bike and one recumbent) and use it to climb 2500 vertical feet of logging roads regularly. And it is fantastic.

Fits 8″ Rim and is 12″ Tall. Commonly used on many different gas scooters, pocket bikes, mini choppers, and go karts. We are on the west coast so the closer you are to the west coast the faster your i…

Consider one of the E-Rad mid-drive kits which include shift sensing (physical shift sensing) and offer both throttle and cadence activated assist… yes, it’s not as good as Bosch, Impulse or Brose which offer torque or advanced multi-sensor activation but none of these are available aftermarket. Yes, E-Rad looks like the 8Fun BBS02 but it’s actually custom and the shift sensing is worth it in my view, along with the variable widths for use with more frame types. Since you mentioned mostly pedaling, get a 500 or 750 watt kit and stick with the first or second assist level… if you buy the 1,000 watt kit it costs more money and makes the bike illegal in most states plus in my experience it’s just overkill

I bought a 2015 GNG mid drive, and the clutch in the crankset freewheel stopped working within a week with barely any riding at all, and I wasn’t even pedaling that hard. Pedaling now does nothing. I emailed GNG, and they told me to disassemble the clutch, and that would fix it. Anyone else have this problem?

Hi Dave! I’m a big fan of Pedego to be honest. Yes, their battery placement isn’t ideal and the prices are a bit higher… but you tend to get very good service, lots of size and color choices, and their battery and motor technology tends to be reliable and powerful. The Magnesium cast wheels are especially cool and useful if you’re heavier, or plan to carry heavy loads, so with your taller and larger body that’s a great option that very few other companies provide. I think you’re definitely on the right track. Do you live near a Pedego dealer?

I didn’t include a charging a section in this article, as this was just about how to build a lithium battery. But here’s a video I made showing you how to choose the appropriate charger for your lithium battery.

Great questions Charles and I have no idea! Sounds like a cool project and I bet people in the Stromer forums could help you with tips. I heard the ST1 models could be unlocked to go faster but I have less experience with the ST2. Adding a front hub motor would be really neat but make sure it works with the larger thru-axle or consider swapping the fork. I think adding suspension would improve the ride a lot and enable a front hub motor but not sure how you’d wire in a second battery or whether you could use the existing one? Would love to hear how it all turns out or see pics someday 😀

Hi Court, I have a 2005 Giant Trance 2 mountain bike I’d like to convert. I want to commute to work which is 15 miles away using trails and minimal road exposure. There is also a fair amount of hills. The trance has a small triangle and I fell I would need a fairly large battery. I see a 52 volt 20ah at Lunacycle that is a triangle that looks like it will fit but its $600. I’m leaning toward a 1000 watt BBSHD unlocked.. all of this said, I recently rode a fat bike with a BionX hub drive that was so smooth I couldn’t believe it. The BioniX battery would never fit the triangle. Any thoughts or guidance would be appreciated. Thanks

Next, plan out your cell configuration on your computer or even with a pencil and paper. This will help ensure you are laying out your pack correctly and show you the final dimensions of the pack. In my top-down drawing below I’ve designated the positive end of the cells in red and the negative end of the cells in white.

  1. A top of the line, tadpole style cargo trike powered by the Bosch Performance mid-drive motor and an 11 speed SRAM drivetrain, optional NuVinci N360 or Harmony continuously variable transmission with Gates Carbon belt drive. The bike leans side to side so you can corner faster and avoid the two-wheel……
    Ideally, I would buy a battery with the same type of connection and just carry the spare one unconnected and swap them over but I don’t seem to be able to find the type of battery case for sale anywhere. It’s a quick release bottle type battery that has two sprung terminals about half inch in diameter that contact with two large terminals on what I think must be the motor controller integrated into the bottom of the bottle mounting bracket.
    Hi Sundaram, I’m not aware of many 18650 LiFePO4 cells, are you sure you are using that chemistry instead of standard lithium ion? Perhaps can you provide a little more detail about the specific cells you’re using?
    Hi What is the best motor for an Recumbent Trike HP Velotechnik Scorpion FS20″? original is an GO SwossDrve Backmotor or an Front midle Motor from Shimano Steps. Both has an Problems.With longer slopes of passages the engines are hot or the battery and the electronics power no longer with, what gives it there for alternative with 25 KMh and max.350Wat?
