I felt that Levitra was amazing! I had mild erectile dysfunction (ED). A dose of 10 mg was probably more than I needed, it was 12-16 hours. I’m 48, 5’10 “160 pounds, good shape, no other medical problems.
This is a great article, I was thinking about making including the batteries and controller in the front Wheel/Motor hub ala (Copenhagen Wheel & FlyKly) and then create something like a solid acrylic or fiber wanted to cover the whole thing and rearrange the batteries.
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.

Hi Court, I have recently purchased a new adult tricycle with the intention of converting it to an electric motor. I am feeling a bit overwhelmed with all the different motor options and configurations available. I want something that will provide me with enough power to get up to speed, and have a long ride time. I have seen YouTube videos where they have linked multiple batteries to get extended ride time. What are your recommendations to get a long ride, with the power for a tricycle and a big rider?
Lithium Ion electric bike batteries are ideal for those that plan to ride longer distances and or more frequent trips. The commuters dream battery, lithium batteries can stand two complete 100% discharges a day for years. Discharging the battery half way riding to work or school, then parking all day at half charge does no damage to a lithium electric bike battery. So the urgency to recharge immediately is not like SLA’s. Since discharging to 100% empty does not significantly harm lithium electric bike batteries, the usable range of the lithium electric bike battery is roughly double that of SLA’s. In typical electric bike use, Li-Ion batteries last from two to four years. Proper storage of Lithium Ion batteries is important when the electric bike will not be used for more than a few weeks. Unplug the battery from the electric bike, charge fully, and then store in a cool but not frozen, dry place.
A custom designed electric trike with large plastic cargo bin at the back, three-speed internally geared hub can be shifted at standstill and is more durable than a traditional derailleur. Two mechanical disc brakes provide good stopping power, max speed limited to 7 mph in……

Warning: if a cheap electric bike is advertised and the advert does not state what kind of battery it has, you can pretty much be certain that it has a lead-acid battery. It might be cheap, but it’s not a bargain. This battery type might be good enough if you want the bike as a mere toy, to be taken out and played with occasionally in your immediate neighborhood – but if not, it would be better to avoid these batteries altogether.
Hi Jasmine! Interesting question, I think you could use a geared hub motor mounted in a 20″ wheel but am not sure if that would match your wheelchair perfectly or mount to a side axle vs. one that’s built into the hub (most ebike hub motors I’ve seen are permanently fixed to the axle). Lots of companies offer basic motor, battery, controller kits but this one from Dillenger appears to come in the small 20″ wheel size. Maybe there’s a way to add a mounting system between the two rear wheels to have this third wheel act as power? The other challenge is reverse, most electric bikes don’t offer this but one company called E-BikeKit does with their trike conversion kit here which may also come in 20″ wheel size. I hope this helps you get started, if you call the E-BikeKit company ask for Jason and maybe he can even give you some more advice as they offer some models designed to be more like personal mobility trikes vs. fast commuter bikes. One such model is their Liberty Trike here.
Hey Court – I would have replied sooner but I wasn’t notified you had replied, guess I will have to check this site more often. I never thought of a front drive system before, I will check it out. From what your article said, I think I can still pedal and probably need to to go up a 8% grade. I like the idea of being able to simply detach the battery and the hub when I put it in the boat. I am going to look around for a more powerful motor as I need to get it up to closer to 28 mph if possible. Just did the ride yesterday and let me tell you the whole way I was like, “need that ebike NOW” If you have any other thoughts let me know….. Thank you, Eric
Cool project! I’d check out electric rider (www.electricrider.com) as I know they have some good electric rickshaw and electric tricycle kits. You’re looking for a strong 48V motor that is geared really low. You want torque, not speed. With slow speed, something in the 1,000 – 1,500W is probably enough. Just don’t expect to be flying down the road…
This is a new one, and promises to be no better than the Li-ion battery type in terms of range, weight, or price. However, it can be molded into interesting shapes. They contain no liquid, so they don’t require the heavy protective cases that other batteries need. Also, this absence of free liquid theoretically means that they should be more stable and less vulnerable to problems caused by overcharge, damage or abuse. In general, they seem to be ideal for use in high capacity, low power applications – such as electric bikes.
18650 cells, which are used in many different consumer electronics from laptops to power tools, are one of the most common battery cells employed in electric bicycle battery packs. For many years there were only mediocre 18650 cells available, but the demand by power tool makers and even some electric vehicle manufacturers for strong, high quality cells has led to the development of a number of great 18650 options in the last few years.
Power: 500W / 36V. Allow you to swap two power modes between the full 500W power to 750W power by a single blue switch wire is embedded in controller. (Only for Twist Throttle). Still remain the full 500W power with no speed control.
Either way works, but my orange jig saves me one hot glue step which just makes for a cleaner looking pack. Of course it’s all the same after the pack gets covered with shrink wrap, so you can use any method you’d like. I’ve even found that some of those cylindrical ice cube trays are perfectly sized to hold 18650 cells. Cutting off the top would leave it clear for welding. I’d add some strong neodymium magnets to the backside to hold the cells in place like my orange jig has, but other than that it’s a perfect jig almost as-is.
The BMS is for 7S, I connect B1+, B2+, B3+, to the negative of the first serie. B4+ is connected to the positive of the first serie, B5+ positive of 2nd serie, B6+ positive of 3rd serie, B7+ positive of 4rd serie.
Hi Pete! I did really enjoy the Neo line and it seemed like they sold a lot of them so hopefully there will be packs available for several years. Considering that the same pack was used on all of the different models, I feel like you should be in great shape 🙂
If not possible, try charging them individually. Some of them might come back but others might be dead. The tricky thing is that they will likely not be able to deliver their full capacity anymore and the actual capacity will likely vary from cell to cell. Two year old cells at a very low voltage are quite a gamble.
E-bikes can also provide a source of exercise for individuals who have trouble exercising for an extended time (due to injury or excessive weight, for example) as the bike can allow the rider to take short breaks from pedaling and also provide confidence to the rider that they’ll be able to complete the selected path without becoming too fatigued.

I am planning on making a 6S2P LifePO4 pack that has a voltage of 19.2V. I have a 6 cell BMS that does balancing (and that is intended to work with 6 LifePO4 cells). I need some help selecting a charger to charge this pack, however, particularly regarding the charger’s voltage specification.
