1500 mile update NeoJumper 26"

Well, it’s been 1500 miles on my Neo Jumper and 1 year 3 months.
I’m very happy with the bike, although there have been problems.
Mountain biking is why I purchased this bike, and it’s my main use.

The suspension handles rocky trails well. It is best to hit obstacle head-on, as the fairly upright geometry of the head/front seems to make maneuvers more squirrelly than I experience on my regular mountain bikes. I find I need to ride with my weight further back on this bike on technical sections than on others. At best I’m only an intermediate rider, so others may have a difference experience.


Range has improved after I burnt out the original control unit around 1200 miles. After 16 miles my 9Ah battery drops to the last bar. The batteries will have more cycles if we don’t drop them below 80%, which I definitely want to do as the cost of new batteries run in the $400-500 range. I also have a 12 Ah battery, which drops to 2 bars remaining around the 18 mile mark. This is on dirt with a 500 ft elevation gain, my weight is around 200 lbs, and average around 12 miles per hour (although I normally have a couple of nice downhill sections where I can reach 25-30 mph).


As noted, I did have warranty work needed. The controller is below the key, and mine had melted wire insulation and minor charring. It stopped working with little warning after 1200 miles. It was nice the bike pedals well with no assist, as I was several miles from home.


I have learned to pedal with a steady cadence. I’ve always anticipated climbs, so shift down to maintain a steady pace. The bike seems to respond best to this steady torque. I will notice some surging if I pedal with a slow cadence or don’t shift down. Response is better if I use a smaller front gear selection; I’m guessing this helps the sensitivity of Torque Sensor. I do try to keep the Torque Sensor clean and adjusted to proper N-m settings of 1 Nm for the two small bolts and 10 Nm for the three larger bolts. It seems to help the responsiveness.


I did replace the saddle soon after purchase. I’ve always done well with Performance Bike Soft Tail saddle, which is the one I use.

I also replaced the pedals with the Xpedo and have been very happy with them (http://www.amazon.com/gp/product/B003RLJG7W?psc=1&redirect=true&ref_=oh_aui_detailpage_o05_s00 ). It has been hard for me to find pedals I like, so am happy I found these. After too many crashes being clipped in I know clip on pedals are not for me.

Water is a must for me. I ended up putting a water bottle cage on the front handle bars. The model I went with is the “M-wave” (http://www.amazon.com/gp/product/B001NGD56G?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00 ).

I do use shock cord to hold my bottle in the cage, and it has handled rough trails with little problems.

I use lights mostly so others see me, so I added the Planet Bike 3 LED white on the front, and the Super Blinky on the back. I also purchased one of the Cree front lights for night rides; it is amazingly bright and was less than $10 (http://www.amazon.com/gp/product/B008KUXRAW?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00 ).


I use the bike in “eco” mode almost all of the time. The only time I use the throttle is when I am walking the bike up a steep hill

I am not trying to ride fast, but ride far.


I am very happy with my NeoJumper, and think I made the right choice.

Excellent report Mike - very informative. Regarding:

What kind of torque wrench do you use for adjusting the torque sensor bolts? I have a thread going on about this topic, and everyone is telling me to not mess with it, and that I'd need a very expensive torque wrench to achieve BH's proscribed tolerances.

I'm using a Venzo Bike Torque Wrench, which costs around $50.
Amazon: http://www.amazon.com/VENZO-Bicycle-Torque-Wrench-Socket/dp/B00811WQT8

Setting a torque of 1 N-m does concern me, so I very seldom adjust the the Hall Torque Plate. And only do so after cleaning doesn't clear up the sensitivity.
This particular style of torque wrench does have a zeroing function, which I'm careful to reset each time. I did practice sensing the click of the wrench before using. I am happy with the torque wrench.

Thanks for all the good info. I just upgraded from a Neo Xtreme to a Neo Jumper 27.5 specifically for better single track performance, so I am glad to know its working out for you. The battery performance you cite seems normal. You can't do much better unless riding slow with few stops on level pavement. Have you needed to adjust the air in the shocks ever?

Thanks for the comments.
I do indeed need to adjust the air in the shocks, as well as in the tires. I get the best response with the lowest amount of air.
I weigh around 200 lb, and keep the rear shock around 160 lb or lower.
I ride it like a downhill style bike, so I'll take obstacles head on, which seems to work well.
I'm happiest on trails classified as intermediate.

Rolling hills


More single track (about the level I like)

Im close to that also, surprising tire wear, it is just now starting to show and thats mostly road riding. A few small adjustment issues, now and then, a skipping of the motor that eventually straightens out after switching on and off. Biggest difference for the better? Meetlocks pedals, http://www.amazon.com/gp/product/B00N3PM3QI?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00
I put an Bell 310 seat post rack, http://www.big5sportinggoods.com/st...-rack/6196125070033/_/A-5314950?#.Vc96NXhRLYs and strap a small cooler on the back with my lock underneath. Handlebar real estate is scarce, I ALWAYS record my rides with a bar mounted ION camera to protect myself, And I also have the cree headlight http://www.amazon.com/gp/product/B00GJZ015Y?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00 that has a lifetime warranty since I ride in the dark after the fall time change. ( I did break the light mount when I dropped my bike and they did replace it under warranty)
The battery in the pic is off my wifes Jet
