Heavy ebike
 

Hi All

I am new here and have an ebike that has 24" wheel. I have problems controling it as the front mounted battery is very heavy. n being 5.6feet height. Its no problems cycling alone but when i have a pillion, the bike gets shaky. would changing it to a 18" alloy ebike wheel 18X2.125 or 18x2.5 work? This i hope would shift the center of gravity lower. any pros or cons? please advise. thanks!

What battery are you using? Changing your wheel size to improve your ride sounds drastic. Can you post some pics and information on your bike so we can disect your problem?

If you feel up to the challenge, relocating the battery to another area on the bike could help tremendously with controlling the bike. Many with Diamond Frame bikes like to mount their batteries in the frame since they have a lower center of gravity than sitting on top of a rear rack. I have the Currie conversion kit with rear mounted battery rack where the batteries are placed into holders on the side of the rack rather than the top and this makes it much easier to handle the bike. In your case, even setting the battery on top of a rear rack would probably give you more control. Moving the battery may require that you rewire. If you don't feel comfortable are there any bike stores in your area willing to work on e-bikes? I think relocating the battery would be the best option for improving control. Good luck.

I do believe that relocating the battery to the rear would be your best bet. My battery is mounted on a front rack, however my battery doesn't weigh a lot.

thanks for the replies, i think it must be the batteries. i got other bikes with batterier located elsewhere without this problem. heres a pic of the bike. thanks

hi

mine are SLA batteries. If theres pictures of how the end result would look, please attached them. I would have to be able to lock the batteries as they are prone to thefts.

If you can't easily move the batteries... maybe it's worth upgrading to a lighter weight battery. SLAs are very heavy and that's not helping your situation. If you switch to NiMh or Li-Ion it will not only make the bike lighter and easier to handle, but they'll last much longer. You could probably get them inside that large battery compartment...
